re_escape escapes all special characters in a string. This function is useful when you want to treat a
string literally in a regular expression context, escaping characters that would otherwise be interpreted as special
regex operators.
Arguments
- pattern
A character vector where each element is a string in which special regex characters are to be escaped.
Value
A character vector of the same length as pattern.
Examples
re_escape("a[bc].*d?")
#> [1] "a\\[bc\\]\\.\\*d\\?"
re_escape(".^$|*+?{}[]()")
#> [1] "\\.\\^\\$\\|\\*\\+\\?\\{\\}\\[\\]\\(\\)"
