R: Remove matched patterns

str_remove {stringr}

R Documentation

Remove matched patterns

Description

Remove matches, i.e. replace them with "".

Usage

str_remove(string, pattern)

str_remove_all(string, pattern)

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 vignette("regular-expressions"). Use regex() for finer control of the matching behaviour.

Match a fixed string (i.e. by comparing only bytes), using fixed(). This is fast, but approximate. Generally, for matching human text, you'll want coll() which respects character matching rules for the specified locale.

You can not match boundaries, including "", with this function.

Value

A character vector the same length as string/pattern.

Examples

fruits <- c("one apple", "two pears", "three bananas")
str_remove(fruits, "[aeiou]")
str_remove_all(fruits, "[aeiou]")
