Remove matches, i.e. replace them with "".
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"). Useregex()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 wantcoll()which respects character matching rules for the specified locale.You can not match boundaries, including
"", with this function.
See also
str_replace() for the underlying implementation.
Examples
fruits <- c("one apple", "two pears", "three bananas")
str_remove(fruits, "[aeiou]")
#> [1] "ne apple" "tw pears" "thre bananas"
str_remove_all(fruits, "[aeiou]")
#> [1] "n ppl" "tw prs" "thr bnns"
