R Documentation

Remove empty rows and columns from a REDCap dataframe

Description

Removes any columns which contain only NA. Likewise, rows are removed in a similar fashion but any REDCap factor fields (record_id, redcap event/repeat) are ignored.

Usage

rc_strip(
  record_data,
  columns = TRUE,
  rows = TRUE,
  factor_cols = NULL,
  id_field = getOption("redcap_bundle")$id_field
)

Arguments

`record_data`	Dataframe. Record data exported from REDCap
`columns`	Logical. When `TRUE`, empty columns will be removed.
`rows`	Logical. When `TRUE`, empty rows will be removed.
`factor_cols`	Character. Column names to ignore when looking for empty rows. By default, the id_field and the REDCap event/repeat columns will be used.
`id_field`	Character. The name of the record_id field for your REDCap project.
