prep_expand_codes: Expand code labels across variables

Description

Code labels are copied from other variables, if the code is the same and the label is set only for some variables

Usage

prep_expand_codes(
  meta_data = "item_level",
  suppressWarnings = FALSE,
  mix_jumps_and_missings = FALSE
)

Value

data.frame an updated metadata data frame.

Arguments

meta_data

data.frame the data frame that contains metadata attributes of study data

suppressWarnings

logical show warnings, if labels are expanded

mix_jumps_and_missings

logical ignore the class of the codes for label expansion, i.e., use missing code labels as jump code labels, if the values are the same.

Examples

if (FALSE) {
load(system.file("extdata", "meta_data.RData", package = "dataquieR"))
meta_data$JUMP_LIST[meta_data$VAR_NAMES == "v00003"] <- "99980 = NOOP"
md <- prep_expand_codes(meta_data)
md$JUMP_LIST
md$MISSING_LIST
md <- prep_expand_codes(meta_data, mix_jumps_and_missings = TRUE)
md$JUMP_LIST
md$MISSING_LIST
load(system.file("extdata", "meta_data.RData", package = "dataquieR"))
meta_data$MISSING_LIST[meta_data$VAR_NAMES == "v00003"] <- "99980 = NOOP"
md <- prep_expand_codes(meta_data)
md$JUMP_LIST
md$MISSING_LIST
