Skimr error message when I try to do skim() with the data exported from REDCap

I would like to use the skimr package and skim() function to explore my data exported from REDCap, but it gives me this error message.

Error in `dplyr::summarize()`:
! Problem while computing `skimmed = purrr::map2(...)`.
ℹ The error occurred in group 4: skim_type = "numeric".
Caused by error:
! Can't combine `..1$numeric.p0` <labelled> and `..2$numeric.p0` <labelled>.
✖ Some attributes are incompatible.
ℹ The author of the class should implement vctrs methods.
ℹ See <https://vctrs.r-lib.org/reference/faq-error-incompatible-attributes.html>.

This is happening because the data are of class labelled. I'd have to understand more of the specifics of Redcap data formatted but I would suggest that for the purposes of skimming an easy solution is to convert to one of the standard data types.
