Add labels from proc_format file to SAS data file

Add labels from proc_format file to SAS data file

add_proc_format_labels(
  df,
  proc_format,
  as_factor = FALSE,
  varname_case = c("lower", "upper"),
  debug_level = 0,
  ...
)

Arguments

df	Input data frame read from haven::read_sas
proc_format	Either path to SAS file with proc format statements or the results of read_proc_format.
as_factor	Convert labelled variables to factor with haven::as_factor?
varname_case	SAS variable names are not case-sensitive, but R variable names are. Choose one of "lower" or "upper" case to normalize the variable names in df and the varnames column of proc_format. Or set equal to NULL to leave both as-is.
debug_level	Default is 0. Level 1 prints confirmation of reading proc_format file. Level 2 prints confirmation that the labels were applied to each variable in df.
...	Arguments passed on to read_proc_format file Path to proc format file. verbose Writes out file path being read. May be removed in the future. missing_values Possible SAS values that should be treated as missing.
