Format REDCap variable labels
Description
Use these functions with the format_labels
argument of
make_labelled()
to define how variable labels should be formatted before
being applied to the data columns of redcap_data
. These functions are
helpful to create pretty variable labels from REDCap field labels.
-
fmt_strip_whitespace()
removes extra white space inside and at the start and end of a string. It is a thin wrapper ofstringr::str_trim()
andstringr::str_squish()
. -
fmt_strip_trailing_colon()
removes a colon character at the end of a string. -
fmt_strip_trailing_punct()
removes punctuation at the end of a string. -

which REDCap uses for special "field embedding" logic. Note thatread_redcap()
removes html tags and field embedding logic from field labels in the metadata by default.
