stri_replace_all_charclass: Replace Occurrences of a Character Class

Description

Replaces with a replacement string every/first/last the characters that fall into a class specified by pattern.

Usage

stri_replace_all_charclass(str, pattern, replacement, merge = FALSE)
stri_replace_first_charclass(str, pattern, replacement)
stri_replace_last_charclass(str, pattern, replacement)

Arguments

str

character vector with strings to search in

pattern

character vector specifying character classes to match, see stringi-search-charclass

replacement

character vector of strings to replace with

merge

logical [stri_replace_all_charclass only]; should consecutive matches be merged into a single one?

Value

• Each function returns a character vector.

Details

Vectorized over str, pattern, and replacement.

These functions scan the input string for matches of a character class. Input that is not part of any match is left unchanged; each match is replaced in the result by the same (fixed) replacement string.
