Changelog

teal 0.13.0

Breaking changes

  • The use of datasets argument in modules has been deprecated and will be removed in a future release. Please use data argument instead. data is of type tdata; see “Creating custom modules” vignettes and function documentation of teal::new_tdata for further details.
  • Due to deprecation of chunks in teal.code, the teal framework now uses their replacement (qenv) instead. The documentation in teal has been updated to reflect this and custom modules written with chunks should be updated to use qenv.
  • Due to deprecation of chunks in teal.code, get_rcode, get_rcode_srv, and get_rcode_ui have been removed.

New features

  • Added the validate_inputs function that transfers input validation messages to app output.
  • modules argument of init accepts teal_module type of object. There is no need to wrap up a single module in modules() or list().
  • Updated module_nested_tabs so that only active modules are calculated in a teal app.

Miscellaneous

  • Updated examples to use scda.2022.
  • Added R session information into a link in the footer of teal applications.
  • Added data hashing step using rlang instead of digest package to calculate the hash (which has been moved from teal.data and teal.slice). There is now an explicit hashing check in the reproducible code output.
  • Removed deprecated functions: root_modules, default_filter, bookmarkableShinyApp, as well as deprecated logging mechanism, including the functions log_app_usage and .log.
  • Updated the “Teal and Bootstrap Themes” vignette to provide more details customizing a teal app with bslib::run_with_themer.
  • Removed outdated diagram from srv_nested_tabs documentation.
  • Changed default values of header and footer arguments in init to empty text.

teal 0.12.0

New features

  • Added the support for custom bslib bootstrap themes in teal::init apps, please read more in the new teal-bs-themes vignette.

Enhancements

  • Added the option to choose which variables can be filtered in the filter panel by using the filterable attributes for the per-dataset lists in the filter argument of init.
  • Updated teal_module to have data argument which receives a list of reactive filter data with "code" and "join_keys" attributes.
  • Updated teal_module to have filter_panel_api argument which receives a FilterPanelAPI object.
  • Updated the internals of module_teal to reflect changes in teal.slice.

Breaking changes

  • Updated teal_module to no longer receive datasets object in the ... argument. In order to use datasets in the teal_module please specify datasets explicitly.
  • Deprecated merge_expression argument in get_rcode_srv function and removed it in get_rcode function.
  • Deprecated session argument in get_rcode function.

Miscellaneous

  • Enhanced the burger button so it is disabled when the filter panel is not used.

teal 0.11.1

Enhancements

  • Added new function reporter_previewer_module to wrap the teal.reporter package previewer functionality as a teal module.
  • Updated teal to support modules which include reporting. If any module which supports reporting is included then a reporter_previewer_module is included.
  • Added default arguments to module() and the server argument is now a function where the second argument can be ... or datasets.

Breaking changes

  • Deprecated bookmarkableShinyApp. In future releases the teal framework will stop supporting shiny bookmarking (which has not officially been supported); it may be officially supported in the future. Note the filter panel in teal.slice retains its ability to save and restore its state if used in a standalone shiny app with bookmarking.

Miscellaneous

  • Added a template to the pkgdown configuration.
  • Removed unneeded shinytest app tests.
  • Updated package authors.
  • Added package vignettes.

teal 0.11.0

  • teal.data: creating and loading the data needed for teal applications.
  • teal.widgets: shiny components used within teal.
  • teal.slice: provides a filtering panel to allow filtering of data.
  • teal.code: handles reproducibility of outputs.
  • teal.transform: standardizes extracting and merging data.
  • teal.logger: standardizes logging within teal framework.

The teal package contains the code to create apps (teal::init), to create a module (teal::module) and to group modules in the app (teal::modules). teal depends on teal.transform and teal.data which contain the functions that teal app creators are likely to need. The other package teal only imports from and therefore teal module creators should either fully specify functions from these packages when required or import them into custom packages as library(teal) will not load them.

New features

  • A simple new teal module named example_module has been included in the package.

Breaking changes

  • teal package has been split into multiple smaller packages, see above.
  • Deprecated root_modules function, users should use modules directly inside init.
  • Due to deprecation of root_modules any label argument to modules must be explicitly named. For example modules("lab", mod1, mod2) should be replaced with modules(label = "lab", mod1, mod2).

Miscellaneous

  • Minor changes to internals of teal: main module panel now has fixed shiny name root and the active tab is named active_tab not Active_tab.
  • MultiAssayExperiment is now suggested packages, not required. Objects dependent on MultiAssayExperiment are changed to lazy-load this now suggested package.

Bug fixes

  • Showing R Code no longer shows reproducibility warning message if reproducibility check has passed.

teal 0.10.1

Breaking changes

  • Changed the HTML identifiers of teal modules - now each nested module receives its own shiny namespace.
  • Deprecated all functions related to connectors that have been moved to their own separate packages.
  • Removed raw_dataset, raw_dataset_connector, named_dataset, named_dataset_file, named_dataset_connector, relational_dataset, relational_dataset_file, relational_dataset_connector, key, as_cdisc, as_cdisc_relational.
  • Removed rcd_connection and rcd_data; scda_dataset_connectors can be passed into cdisc_data and teal_data directly.
  • Replaced rcd_dataset_connector and rcd_cdisc_dataset_connector with scda_dataset_connector and scda_cdisc_dataset_connector respectively.
  • Renamed teal_show_js_log option into teal.show_js_log to match options naming convention.
  • Removed %is_in% and stop_shiny internal utility functions.

New features

Logging
  • Added support for logging using the logger package.
  • Added a new function register_logger, which registers a logger in a given namespace.
  • Added trace and info levels log messages to the teal framework.
  • Added pid and shiny session token into footnote so app developers can identify logs for apps.
Other

  • Added print methods to the DatasetConnector, RelationalData, RelationalDataconnector and JoinKeys classes and added input validation to the implementation of the print method that was already in the Dataset object.

  • Added public facing constructor functions for CDISCDataConnector, RelationalDataConnector, and DataConnection classes.

  • Modified data_extract_spec to allow both the filter and select parameters to be NULL, which results in the data_extract_ui acting as if a filter_spec with all variables as possible choices had been supplied as the filter argument and a select_spec with the multiple parameter set to TRUE had been supplied as the select argument.

  • Added support of the full screen for a module when the filters argument is equal NULL.

  • Added support for shiny::moduleServer passed to the server parameter of teal::module.

  • Added teal.threshold_slider_vs_checkboxgroup as an R option: if a categorical variable has more than this number of unique values, the filter panel uses a drop-down select input instead of a checkbox group.

  • Extended the FilteredData API to allow managing filter states programmatically and not only from the UI of a teal application.

  • Hid the buttons to remove filters from all datasets and each dataset when there are no active filters.

  • Updated init to accept RelationalData, data.frame, MultiAssayExperiment, Dataset, DatasetConnector, list or a function returning a named list as data input.

Bug fixes

  • choices_selected now correctly removes duplicates from the array passed to its choices parameter.
  • Fixed call returned by FilterState in case of using MultiAssayExperiment::subsetByColData. Now single condition for variable containing NA values is !is.na(var) & var == <condition>.
  • Fixed data loading of DatasetConnector being dependent on other Dataset or DatasetConnector objects.
  • Fixed restoring a bookmarked filter state of teal application.
  • Refactored module_nested_tabs to fix the issue with the filter panel not reacting to an input change in a nested module.

  • Fixed setting JoinKeys when key name between two Dataset object differs.
  • Fixed printing of the JavaScript console logs to the R console when teal.show_js_log = TRUE.

Miscellaneous

  • Soft-deprecate mae_dataset() in favor of more general dataset() constructor.
  • Added a vignette describing the modifications to teal applications users can apply using R options.
  • Added default values to the label argument of select_spec and filter_spec.
  • Added validation to FilteredDataset::get_data to accept logical input only.
  • Changed references to outdated functions of teal.devel in the documentation.
  • Introduced a Teal prefix to all public R6 classes to avoid name collisions with other packages.
  • Removed dependency on utils.nest and replaced its functionality in teal with equivalents from the checkmate package and base R.
  • Replaced the old shiny server functions of DataConnection, RelationalDataConnector, DatasetConnector, and RelationalData with the shiny::moduleServer equivalents.
  • Running a teal application via ui_teal_with_splash and srv_teal_with_splash is now no longer recommended because it doesn’t support new features (e.g. logging, bookmarking). Use init instead.
  • Updated the R version requirement to >= 4.0.
  • Updated the “filter panel collapse” icon to remove warnings when using shiny version >= 1.7.
  • Removed some of the non-exported, debugging modules.
  • Updated the footer tag style to be less visible.

  • Added split and merge methods to the JoinKeys object.
  • Added all_choices() as a possible argument to the selected parameter of filter_spec, select_spec and choices_selected indicating that all choices are selected.
  • The append method of a CodeClass object has been modified to print a warning message when the argument does not result in any code being added because it is duplicated.
  • Implemented delayed functionality to the mutate method of the Dataset and DatasetConnector objects.
  • Modified teal_data to return a CDISCData object whenever any of its arguments is a type of CDISCData object.
  • Updated filters to show both levels of a logical variable TRUE/FALSE even if one is missing from the original array.

Miscellaneous

Enhancements

  • Added informational stop message when using mutate_data with RelationalDataConnector.
  • Modified as_cdisc to behave similarly to cdisc_dataset when called on a Dataset object.
  • Changed the displayed format of the data name and the column name in data_extract_spec UI elements. Both are now compressed to <data name>.<column name> if they don’t change during runtime of the app.
  • Added ADSAFTTE to the list of recognized ADaM dataset names.
  • Added another example to data_extract_spec’s doc string showcasing app users can choose a variable used for filtering in the encoding panel.
  • Added CSS styling to tool tips in teal modules.

Bug fixes

  • Fixed a bug that crashes app whenever a Date or datetime column is selected from a filter_spec.

teal 0.9.4

Enhancements

  • Released snowflake connection and connectors.
  • Changed ordering of datasets to be more intuitive (topologically first for CDISC datasets only and then according to input datasets order).
  • When closing a teal app (ending a user shiny session), all DataConnections will now try to close their connections.
  • Added ADHY keys to configuration file.
  • Extended the filter_spec function: the parameter choices is no longer mandatory (the function will take all possible choices by default) and the vars parameter additionally accepts the choices_selected and allows to change the variables for filtering using the UI elements in the encoding panel.

Bug fixes

  • Cleaned up imports in the package.
  • Modified value_choices function to handle edge case when "NA" and NA values exist in the character column that choices are derived from.

Enhancements

  • Added button to remove all active filters from the Filter Panel.

teal 0.9.2

New Features

  • Added python_dataset_connector to create delayed data objects from python scripts or directly from python code.
  • NOTE: python_dataset_connector is not yet ready to be deployed on RSConnect because it does not contain numpy and pandas, which are Python libraries used in python_dataset_connector.
  • Added support for filtering on Date and Datetime variables in the Filter Panel.
  • Added buttons for date and datetime filter widgets to reset the value to the original.
  • Added new function check_key_duplicates, which creates a short summary about rows with duplicated primary key (row numbers and the number of duplicates)

  • Fixed mutate_data to accept the whole scope of objects for vars.
  • Clarified teal::init function documentation to state that custom css loading code with htmltools::htmlDependency should be included in the header argument rather than inside ui arguments of modules.
  • Enabled empty select field inside data_extract_spec.
  • Added new argument drop_keys to filter_spec to decide whether to drop or keep keys columns on single filter on those columns.
  • Added a new optional argument keys to variable_choices. keys specifies the names of the variables, which should have the new key icon shown next to them in the variable drop down menus in the left-hand side encoding panels instead of the icon appropriate for their original R variable type. variable_choices now also works with RelationalDataset and RelationalDatasetConnector objects.

Miscellaneous

  • Removed include_factors option in get_class_colnames in RawDataset.

teal 0.9.1

  • Adds method to resolve nested lists containing delayed data objects, which can be used for arm_ref_comp objects.
  • Nested tabs module now has better alignment with the filter panel on the page.

  • Fixes the issue with connection close code not being present in get_code results.
  • Fixes the issue of occasional incorrect ordering of bar charts on the filter panel.
  • More informative error displayed when pull_fun of DataConnection produces an error.

teal 0.9.0

  • cdisc_dataset and dataset now return R6 class objects (RelationalDataset).

  • A new teal_data function to include datasets and connectors into teal application.

  • cdisc_data function to include datasets and connectors into teal application where a check argument still could be used and other consistency tests are performed.

  • get_raw_data can be used to derive raw data from R6 objects e.g. (RelationalDataset).

  • RawDatasetConnector, NamedDatasetConnector and RelationalDatasetConnector to execute custom function call in order to get data from connection.

  • CodeClass to manage reproducibility of the data and relationships between datasets. Not directly exposed to the public interface.

  • mutate_dataset allows to modify dataset or connector via code argument or an R script.

  • mutate_data allows to change any dataset in RelationalData, RelationalDataConnector or RelationalDataList.

  • New wrapper functions to manipulate RelationalDatasetConnector and RelationalDataset such as get_dataset, load_dataset, as_relational.

  • New wrapper functions to manipulate RelationalDataConnector, RelationalData and RelationalDataList such as get_datasets, load_datasets.

  • choices_labeled, filter_spec, select_spec, data_extract_spec, value_choices, variable_choices as S3 class applied on data.frame and also on delayed data.

  • You can no longer modify the app$datasets, but must instead use argument filter in the init function.

  • New modules were created to create a module of nested teal modules, then another one that adds the right filter pane to each tab. The teal::init function stays unchanged.

  • The teal::init function now returns a UI function with an optional id argument. This allows to embed it into other applications. A split view of two teal applications side-by-side is one such example and shown in a vignette. teal::init was turned into a wrapper function around module_teal_with_splash.R and developers that want to embed teal as a Shiny module should directly work with these functions (ui_teal_with_splash and srv_teal_with_splash) instead of teal::init.

  • The teal::init function now has a title parameter to set the title of the browser window.

  • Missing data NA is now explicitly addressed in the filter panel: NAs are excluded by default and a checkbox to include them was added.

  • Statistics of the data are visually depicted in terms of histograms or bar charts overlayed onto the Shiny input elements.

  • Added buttons to remove all filters applied to a dataset.

  • Restored the functionality to hide the filter panel for a module when it was constructed with filters = NULL.

  • Moved helper functions into utils.nest and removed unused functions set_labels_df and get_labels_df.

  • optionalSelectInput now allows for grouped choices.

Refactor of FilteredData (for developers)

  • FilteredData is now fully reactive. Now filtered data is lazy evaluated as per need. This further opens the door to bookmarking teal apps (bookmarking currently works for the right filtering panel, but we will make this feature more sophisticated in a future release, each module must be reviewed and adapted if it contains reactiveValues).
  • Datasets and materialized connectors are provided to FilteredData by set_datasets_data function located in init_datasets.R file.
  • Renamed get_dataset() method to get_data().
  • Renamed get_filter_call() method to get_filter_expr(); returns an expression rather than a list.
  • Removed argument isolate from get_data() method and similar methods. You must isolate it yourself as needed. If you want to temporarily deactivate Shiny errors due to missing errors, you can set options(shiny.suppressMissingContextError = TRUE). In general, avoid isolate as this breaks reactivity.
  • We added a development module to add several filters at once, e.g. safety filters. This is to be evaluated before it is converted into a proper module and made available to end-users.

teal 0.8.5

  • UI bug fix to hide filter elements for not used datasets.
