Bug fixes and stability enhancements
  • dfm() returns a dfm with the identical column order even if tokens_compound() or tokens_ngrams() is used in the upstream (#2100).
  • dfm_group() with NA values in a grouping variable now drops those, similar to the behaviour of tokens_group() and corpus_group() (#2134).
Changes and additions
  • char_wordstem() now has a a new argument check_whitespace, which will not throw an error when lower-casing text containing a whitespace character.
  • dfm_remove() now has a new argument padding = FALSE that when TRUE, collects counts of the removed features in the first column. This produces results consistent with what is compiled as a dfm built from tokens where some have been removed with padding = TRUE (#2152).
