Replace matched patterns in a string

Dependency-free drop-in alternative for stringr::str_replace_all().

Usage

str_replace_all(string, pattern, replacement)

Source

Adapted from the stringr package.

Arguments

string

Input vector. Either a character vector, or something coercible to one.

pattern

Pattern to look for.

The default interpretation is a regular expression, as described in base::regex. Control options with regex().

Match a fixed string (i.e. by comparing only bytes), using fixed(). This is fast, but approximate.

replacement

A character vector of replacements. Should be either length one, or the same length as string or pattern. References of the form \1, \2, etc. will be replaced with the contents of the respective matched group (created by ()).

To perform multiple replacements in each element of string, pass a named vector (c(pattern1 = replacement1)) to str_replace_all().

To replace the complete string with NA, use replacement = NA_character_.

Using a function for replacement is not yet supported.

Value

A character vector.
