nsentence() method for spacyr parsed objects. (#1289)nsyllable() that incorrectly handled cased words, and returned wrong names with use.names = TRUE. (#1282)summary.character() caused by previous import of the network package namespace. (#1285)dfm_smooth() now correctly sets the smooth value in the dfm (#1274). Arithmetic operations on dfm objects are now much more consistent and do not drop attributes of the dfm, as sometimes happened with earlier versions.tokens_toupper() and tokens_tolower() no longer remove unused token types. Solves #1278.dfm_trim() now takes more options, and these are implemented more consistently. min_termfreq and max_termfreq have replaced min_count and max_count, and these can be modified using a termfreq_type argument. (Similar options are implemented for docfreq_type.) Solves #1253, #1254.textstat_simil() and textstat_dist() now take valid dfm indexes for the relevant margin for the selection argument. Previously, this could also be a direct vector or matrix for comparison, but this is no longer allowed. Solves #1266.dfm_group() (#1295).
