R: Trim something other than whitespace

str_trim_anything {strex} | R Documentation

## Trim something other than whitespace

### Description

The `stringi` and `stringr` packages let you trim whitespace, but what if you want to trim something else from either (or both) side(s) of a string? This function lets you select which pattern to trim and from which side(s).

### Usage

    str_trim_anything(string, pattern, side = "both")

### Arguments

`string` | A character vector.
`pattern` | The pattern to look for. The default interpretation is a regular expression, as described in stringi::about_search_regex. To match a without regular expression (i.e. as a human would), use coll(). For details see `stringr::regex()`.
`side` | Which side do you want to trim from? `"both"` is the default, but you can also have just either `"left"` or `"right"` (or optionally the shortened `"b"`, `"l"` and `"r"`).

### Value

A string.

    str_trim_anything("..abcd.", coll("."), "left")
