These selection helpers match variables according to a given pattern.

  • all_ard_groups(): Use this function in dplyr selecting environments, such as dplyr::select(). Function selects grouping columns, e.g. columns named "group##" or "group##_level".

  • all_ard_variables(): Use this function in dplyr selecting environments, such as dplyr::select(). Function selects variables columns, e.g. columns named "variable" or "variable_level".

Usage

all_ard_groups(types = c("names", "levels"))

all_ard_variables(types = c("names", "levels"))

Arguments

types

(character)
type(s) of columns to select. "names" selects the columns variable name columns, and "levels" selects the level columns. Default is c("names", "levels").

Value

tidyselect output

Examples

ard <- ard_categorical(ADSL, by = "ARM", variables = "AGEGR1")
