Remove Punctuation Marks from a Text Document

Description

Remove punctuation marks from a text document.

Usage

## S3 method for class 'character'
removePunctuation(x,
                  preserve_intra_word_contractions = FALSE,
                  preserve_intra_word_dashes = FALSE,
                  ucp = FALSE, ...)
## S3 method for class '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

data("crude")
inspect(crude[[14]])
inspect(removePunctuation(crude[[14]]))
inspect(removePunctuation(crude[[14]],
                          preserve_intra_word_contractions = TRUE,
                          preserve_intra_word_dashes = TRUE))
