Extract decode tables from data

Usage

extract_decode_tbls_from_data(.data, lvl_to_lbl = "{var}C")

Arguments

.data: data frame
lvl_to_lbl: a named list, where elements correspond to matching names in .data and decode_tbls. One element can be left unnamed to provide the default transformation. Each element should be either: (1) a function/formula; (2) a custom glue specification. The default is "{var}C", which means the label variable name is the level variable name appended with a "C".

Value

decode_tbls
