Bug fixes and stability enhancements
  • fcm() computes the marginal frequency of upper-case tokens correctly (#2176).
  • tokens_chunk() keeps all the docid, including those of empty documents, in the original object.
  • tokens_select() recycles values when the length of startpos or endpos is less than ndoc(x).
  • tokens_lookup() and dfm_lookup() can apply very large dictionaries (more than 100,000 keys).
