To provide some mild support for round-tripping variables between Stata/SPSS
and R, haven stores variable formats in an attribute: format.stata,
format.spss, or format.sas. If this causes problems for your
code, you can get rid of them with zap_formats.
zap_formats(x)
| x | A vector or data frame. |
|---|
Other zappers: zap_empty,
zap_labels, zap_label,
zap_widths
