Resolve delayed inputs by evaluating the code within the provided datasets

Source: R/resolve_delayed.R
resolve_delayed.Rd

[Stable]

Usage 

resolve_delayed(x, datasets, keys)

# S3 method for FilteredData
resolve_delayed(
  x,
  datasets,
  keys = sapply(datasets$datanames(), datasets$get_keys, simplify = FALSE)
)

# S3 method for list
resolve_delayed(x, datasets, keys = NULL)

Arguments

x

(delayed_data, list) to resolve.

datasets

(FilteredData or named list) to use as a reference to resolve x.

keys

(named list) with primary keys for each dataset from datasets. names(keys) should match names(datasets).

Value

Resolved object.

Methods (by class)

  • resolve_delayed(FilteredData): Default values for keys parameters is extracted from datasets.

  • resolve_delayed(list): Generic method when datasets argument is a named list.

Examples 

library(shiny)
ADSL <- teal.transform::rADSL
isolate({
  data_list <- list(ADSL = reactive(ADSL))

  # value_choices example
  v1 <- value_choices("ADSL", "SEX", "SEX")
  v1
  resolve_delayed(v1, data_list)

  # variable_choices example
  v2 <- variable_choices("ADSL", c("BMRKR1", "BMRKR2"))
  v2
  resolve_delayed(v2, data_list)

  # data_extract_spec example
  adsl_filter <- filter_spec(
    vars = variable_choices("ADSL", "SEX"),
    sep = "-",
    choices = value_choices("ADSL", "SEX", "SEX"),
    selected = "F",
    multiple = FALSE,
    label = "Choose endpoint and Censor"
  )

  adsl_select <- select_spec(
    label = "Select variable:",
    choices = variable_choices("ADSL", c("BMRKR1", "BMRKR2")),
    selected = "BMRKR1",
    multiple = FALSE,
    fixed = FALSE
  )

  adsl_de <- data_extract_spec(
    dataname = "ADSL",
    select = adsl_select,
    filter = adsl_filter
  )

  resolve_delayed(adsl_filter, datasets = data_list)
  resolve_delayed(adsl_select, datasets = data_list)
  resolve_delayed(adsl_de, datasets = data_list)

  # nested list (arm_ref_comp)
  arm_ref_comp <- list(
    ARMCD = list(
      ref = variable_choices("ADSL"),
      comp = variable_choices("ADSL")
    )
  )

  resolve_delayed(arm_ref_comp, datasets = data_list)
