Remove Punctuation Marks from a Text Document

Remove punctuation marks from a text document.

Usage

# S3 method for character
removePunctuation(x,
                  preserve_intra_word_contractions = FALSE,
                  preserve_intra_word_dashes = FALSE,
                  ucp = FALSE, …)
# S3 method for PlainTextDocument
removePunctuation(x, …)

Arguments

x: a character vector or text document.
preserve_intra_word_contractions: a logical specifying whether intra-word contractions should be kept.
preserve_intra_word_dashes: a logical specifying whether intra-word dashes should be kept.
ucp: a logical specifying whether to use Unicode character properties for determining punctuation characters. If FALSE (default), characters in the ASCII [:punct:] class are taken; if TRUE, the characters with Unicode general category P (Punctuation).
…: arguments to be passed to or from methods; in particular, from the PlainTextDocument method to the character method.

Value

The character or text document x without punctuation marks (besides intra-word contractions (') and intra-word dashes (-) if preserve_intra_word_contractions and preserve_intra_word_dashes are set, respectively).

Examples

# NOT RUN {
data("crude")
inspect(crude[[14]])
inspect(removePunctuation(crude[[14]]))
inspect(removePunctuation(crude[[14]],
                          preserve_intra_word_contractions = TRUE,
                          preserve_intra_word_dashes = TRUE))
