R Documentation

Call gregexpr on the content of a tm Corpus.

Pull out content of a tm corpus and call gregexpr on that content represented as a list of character strings.

tm_gregexpr(
  pattern,
  corpus,
  ignore.case = FALSE,
  perl = FALSE,
  fixed = FALSE,
  useBytes = FALSE
)

`pattern`	See gregexpr
`corpus`	Either a character vector or tm Corpus object.
`ignore.case`	See gregexpr
`perl`	See gregexpr
`fixed`	See gregexpr
`useBytes`	See gregexpr

If 'corpus' is already a character vector, it just calls gregexpr with no fuss (or warning).

This method gives results exactly as if gregexpr were called on the Corpus represented as a list of strings.
