cards 0.7.0

CRAN release: 2025-08-27

New Features and Functions

• Updated sort_ard_hierarchical() to allow for different sorting methods at each hierarchy variable level. (#487)

• Updated sort_ard_hierarchical() and filter_ard_hierarchical() to always keep attribute and total N rows at the bottom of the ARD.

• Added argument var to filter_ard_hierarchical() to allow filtering by any hierarchy variable. (#467)

• Added flexibility to filter by by variable level-specific values when using filter_ard_hierarchical() to allow for filtering of hierarchical ARDs by difference in two rates. (#438)

• The ard_strata() function has been updated to include the strata columns in the nested data frames. (#461)

• Similar to ard_stack_hierarchical(), ard_stack() contains an args attribute to retain information about input arguments.

• Added an article illustrating how to summarize long data structures. (#356)

• Added ard_stack(.by_stat) and ard_stack_hierarchical(by_stat) arguments that, when TRUE (the default), includes a univariate ARD tabulation of the by variable in the returned ARD. (#335)

• shuffle_ard() passes down the args attribute of the input card object when present. (#484, @dragosmg)

• shuffle_ard() fills overall or group statistics with "Overall <column_name>" or "Any <column_name>". (#337, @dragosmg)

• shuffle_ard() messages if "Overall <column_names>" is accidentally present in the data and creates a unique label. (#465, @dragosmg)

• Add ADLB data set. (#450)

Lifecycle Changes

• The following functions have been renamed. The old functions still work in the package, and will be soft deprecated in the next release. (#470)
  • ard_continuous() to ard_summary()
  • ard_complex() to ard_mvsummary()
  • ard_categorical() to ard_tabulate()
  • ard_dichotomous() to ard_tabulate_value()
• shuffle and .shuffle arguments (for ard_stack_hierarchical() and ard_stack()) are deprecated and users encouraged to call shuffle_ard() directly. (#475, @dragosmg)

cards 0.6.1

CRAN release: 2025-07-03

New Features and Functions

• Added new function ard_identity() for saving pre-calculated statistics in an ARD format. (#379)

Lifecycle Changes

• Updating any fmt_fn references to fmt_fun for consistency.

  • Any function with an argument cards::foo(fmt_fn) has been updated to cards::foo(fmt_fun). The old syntax will continue to function, but with a deprecation warning to users.

  • The following function names have been updated: alias_as_fmt_fun(), apply_fmt_fun(), and update_ard_fmt_fun(). The former function names are still exported from the package, and users will see a deprecation note when they are used.

  • Importantly, the ARD column named "fmt_fn" has been updated to "fmt_fun". This change cannot be formally deprecated. For users who were accessing the ARD object directly to modify this column instead of using functions like update_ard_fmt_fun(), this will be a breaking change.

Bug Fixes

• Fix bug in sort_ard_hierarchical() when hierarchical ARD has overall=TRUE. (#431)

• Fix bug in ard_stack_hierarchical() when id values are present in multiple levels of the by variables. (#442)

• Fix bug in shuffle_ard() where error is thrown if input contains hierarchical results. (#447)

cards 0.6.0

CRAN release: 2025-04-11

New Features and Functions

• Added functions sort_ard_hierarchical() and filter_ard_hierarchical() to sort & filter ARDs created using ard_stack_hierarchical() and ard_stack_hierarchical_count(). (#301)

• Updated ard_stack_hierarchical() and ard_stack_hierarchical_count() to automatically sort results alphanumerically. (#423)

• Added new function unlist_ard_columns(). (#391)

• Updated function rename_ard_columns(). (#380)

  • The function no longer coerces values to character.

  • The fill argument has been added to specify a value to fill in the new column when there are no levels associated with the variables (e.g. continuous summaries).

  • The unlist argument has been deprecated in favor of using the new unlist_ard_columns() function.

  • The function no longer accepts generic data frames: inputs must be a data frame of class card.

• Added function ard_formals() to assist in adding a function’s formals, that is, the arguments with their default values, along with user-passed arguments into an ARD structure.

Bug Fixes

• Fixed sorting order of logical variables in nest_for_ard(). (#411)

Lifecycle Changes

• The shuffle_ard() function no longer outputs a 'label' column, and instead retains the original 'variable' level from the cards object. It also no longer trims rows with non-numeric stats values. (#416)

cards 0.5.1

CRAN release: 2025-03-01

• Small update to account for a change in R-devel.

cards 0.5.0

CRAN release: 2025-02-17

New Features and Functions

• Added functions rename_ard_groups_shift() and rename_ard_groups_reverse() for renaming the grouping variables in the ARD. (#344)

• Added an option to specify the default rounding in the package: cards.round_type. See ?cards.options for details. (#384)

• Added the print_ard_conditions(condition_type) argument, which allows users to select to return conditions as messages (the default), or have warnings returned as warnings and errors as errors. (#386)

• Added the all_ard_group_n(types) argument to allow separate selection of groupX and groupX_level columns.

• Added the tidy_ard_column_order(group_order) argument that allows users to specify whether the grouping variables are listed in ascending order (the default) or descending order. The output of ard_strata() now calls tidy_ard_column_order(group_order="descending").

Other Updates

• A new article has been added detailing how to create new ARD functions.

• Results are now sorted in a consistent manner, by descending groups and strata. (#342, #326)

Lifecycle Updates

• Function label_cards() has been renamed to label_round(), which more clearly communicates that is returns a rounding function.

cards 0.4.0

CRAN release: 2024-11-27

New Features and Functions

• Added functions as_cards_fn(), is_cards_fn(), and get_cards_fn_stat_names(). These functions assist is creating functions with attributes enumerating the expected results.

• Updated ard_continuous() and ard_complex() to return full ARDs when functions passed are created with as_cards_fn(): instead of a single row output, we get a long ARD with rows for each of the expected statistic names. (#316)

• Added function ard_pairwise() to ease the calculations of pairwise analyses. (#359)

Other Updates

• Improved messaging in print_ard_conditions() when the calling function is namespaced. (#348)

• Updated print method for 'card' objects so extraneous columns are never printed by default.

Lifecycle Changes

• No longer exporting functions check_pkg_installed(), is_pkg_installed(), get_min_version_required(), get_pkg_dependencies(). These functions are now internal-only. (#330)

Bug Fixes

• The tidy_ard_column_order() now correctly orders grouping columns when there are 10+ groups. This also corrects an issue in the hierarchical functions where the ordering of the variables matters. (#352)

cards 0.3.0

CRAN release: 2024-10-03

New Features & Updates

• Added functions ard_stack_hierarchical() and ard_stack_hierarchical_count() that ease the creation of ARDs for multiple nested or hierarchical structures. (#314)

• Added functions update_ard_fmt_fn() and update_ard_stat_label() to update an ARD’s formatting function and statistic label, respectively. (#253)

• Added rename_ard_columns(unlist) argument, which unlists specified columns in the ARD data frame. (#313)

• Added ard_strata() function to ease the task of calculating ARDs stratified by one or more other categorical variables. (#273)

• Added functions mock_continuous(), mock_categorical(), mock_dichotomous(), mock_missing(), mock_attributes() to build ARDs in the absence of a data frame. Where applicable, the formatting functions are set to return 'xx' or 'xx.x' to aid in the construction of mock tables or table shells. (#256)

• Added functions for printing results from eval_capture_conditions(). Captured conditions can be printed as either errors or messages with captured_condition_as_error() and captured_condition_as_message(), respectively. (#282)

Other Updates

• The ard_hierarchical_count() function has been updated to match the behavior of ard_hierarchical() and results are now only returned for the last column listed in the variables arguments, rather than recursively counting all variables.

• Add columns 'fmt_fn', 'warning', and 'errors' to ard_attributes() output. (#327)

• Add checks for factors with no levels, or any levels that are NA into ard_* functions (#255)

• Any rows with NA or NaN values in the .by columns specified in ard_stack() are now removed from all calculations. (#320)

cards 0.2.2

CRAN release: 2024-09-02

New Features & Updates

• Converted ard_total_n() to an S3 generic and added method ard_total_n.data.frame().

• Added the bind_ard(.quiet) argument to suppress messaging. (#299)

• Improved ability of shuffle_ard() to populate missing group values where possible. (#306)

• Added apply_fmt_fn(replace) argument. Use replace=FALSE to retain any previously formatted statistics in the stat_fmt column. (#285)

• Added bind_ard(.distinct) argument, which can remove non-distinct rows from the ARD across grouping variables, primary variables, context, statistic name and value. (#286)

Bug Fixes

• Fix in print_ard_conditions() when the variables were factors, which did not render properly in cli::cli_format().

• Bug fix in print_ard_conditions() and we can now print condition messages that contain curly brace pairs. (#309)

cards 0.2.1

CRAN release: 2024-08-17

• Update in ard_categorical() to use base::order() instead of dplyr::arrange(), so the ordering of variables match the results from base::table() in some edge cases where sorted order was inconsistent.

• Update in ard_categorical() to run base::table() output checks against coerced character columns. Previously, we relied on R to perform checks on the type it decided to check against (e.g. when it coerces to a common type). While the initial strategy worked in cases of Base R classes, there were some bespoke classes, such as times from {hms}, where Base R does not coerce as we expected.

• Adding selectors all_group_n() and all_missing_columns(). (#272, #274)

• Added new function add_calculated_row() for adding a new row of calculated statistic(s) that are a function of the other statistics in the ARD. (#275)

cards 0.2.0

CRAN release: 2024-07-20

New Features & Updates

• Converting ard_*() functions and other helpers to S3 generics to make them extendable. (#227)

• Added helper rename_ard_columns() for renaming/coalescing group/variable columns. (#213).

• Added new function ard_total_n() for calculating the total N in a data frame. (#236)

• Added the nest_for_ard(include_data) argument to either include or exclude the subsetted data frames in a list-column in the returned tibble.

• Added check_ard_structure(column_order, method) arguments to the function to check for column ordering and whether result contains a stat_name='method' row.

• Added the optional ard_hierarchical(id) argument. When provided we check for duplicates across the column(s) supplied here. If duplicates are found, the user is warned that the percentages and denominators are not correct. (#214)

• Improved messaging in check_pkg_installed() that incorporates the calling function name in the case of an error. (#205)

• Updated is_pkg_installed() and check_pkg_installed() to allow checks for more than package at a time. The get_min_version_required() function has also been updated to return a tibble instead of a list with attributes. (#201)

• Styling from the {cli} package are now removed from errors and warnings when they are captured with eval_capture_conditions(). Styling is removed with cli::ansi_strip(). (#129)

Bug Fixes

• Bug fix in ard_stack() when calls to functions were namespaced. (#242)

• The print_ard_conditions() function has been updated to no longer error out if the ARD object does not have "error" or "warning" columns. (#240)

• Bug fix in shuffle_ard() where factors were coerced to integers instead of their labels. (#232)

Lifecycle Changes

• Corrected order that ard_categorical (strata) columns would appear in the ARD results. Previously, they appeared in the order they appeared in the original data, and now they are sorted properly. (#221)

• The API for ard_continuous(statistic) and ard_missing(statistic) arguments has been updated. Previously, the RHS of these argument’s passed lists would be either continuous_summary_fns() and missing_summary_fns(). Now these arguments accept simple character vectors of the statistic names. For example, ard_categorical(statistic = everything() ~ c("n", "p", "N")) and ard_missing(statistic = everything() ~ c("N_obs", "N_miss", "N_nonmiss", "p_miss", "p_nonmiss")). (#223)

• Updated ard_stack() to return n, p, and N for the by variable when specified. Previously, it only returned N which is the same for all levels of the by variable. (#219)

• Bug fix where ard_stack(by) argument was not passed to ard_missing() when ard_stack(.missing=TRUE). (#244)

• The ard_stack(by) argument has been renamed to ".by" and its location moved to after the dots inputs, e.g. ard_stack(..., .by). (#243)

• A messaging overhaul to utilize the scripts in https://github.com/ddsjoberg/standalone/blob/main/R/standalone-cli_call_env.R. This allows clear error messaging across functions and packages. (#42)

  • The print_ard_conditions(call), check_list_elements(env), cards_select(.call) arguments have been removed.
