[R] tm::stemDocument function not work

[Ricardo Pietrobon]

thanks Pascal. actually, right after I sent the post I realized that I
didn't send my sessionInfo (at the bottom of this message now). Just
to make sure, everything in my script works except for the line with
stemDocument, which was commented in my gist. Below is the specific
warning I am getting:

> corpus  <- tm_map(corpus, stemDocument, language = "english")
Warning message:
In parallel::mclapply(x, FUN, ...) :
  all scheduled cores encountered errors in user code
