Set of functions to supplement the {tidyselect} set of functions for selecting columns of data frames (and other items as well).
all_continuous() selects continuous variables
all_continuous2() selects only type "continuous2"
all_categorical() selects categorical (including "dichotomous") variables
all_dichotomous() selects only type "dichotomous"
all_tests() selects variables by the name of the test performed
all_stat_cols() selects columns from tbl_summary/tbl_svysummary object with summary statistics (i.e. "stat_0", "stat_1", "stat_2", etc.)
all_interaction() selects interaction terms from a regression model
all_intercepts() selects intercept terms from a regression model
all_contrasts() selects variables in regression model based on their type of contrast
all_continuous(continuous2 = TRUE)
all_continuous2()
all_categorical(dichotomous = TRUE)
all_dichotomous()
all_tests(tests)
all_intercepts()
all_interaction()
all_contrasts(
contrasts_type = c("treatment", "sum", "poly", "helmert", "sdif", "other")
)
all_stat_cols(stat_0 = TRUE)(scalar logical)
Logical indicating whether to include continuous2 variables. Default is TRUE
(scalar logical)
Logical indicating whether to include dichotomous variables. Default is TRUE
(character)
character vector indicating the test type of the variables to select, e.g.
select all variables being compared with "t.test".
(character)
type of contrast to select. Select among contrast types c("treatment", "sum", "poly", "helmert", "sdif", "other").
Default is all contrast types.
(scalar logical)
When FALSE, will not select the "stat_0" column. Default is TRUE
A character vector of column names selected
