However, when I apply it to my corpus using the tm_map function it only stems the last word of each document (The problem is the for wordStem and stemDocument does not work at all).  An example: > path <- c("c:\path\to\directory")       # collection of plain text documents > corp <- Corpus(DirSource(path), readerControl = list(reader = readPlain, language = "en_US" , load = T)) > inspect(corp) A corp...
