R: Remove back-to-back duplicates of a pattern in a string.

str_singleize {strex} | R Documentation

## Remove back-to-back duplicates of a pattern in a string.

### Description

If a string contains a given pattern duplicated back-to-back a number of times, remove that duplication, leaving the pattern appearing once in that position (works if the pattern is duplicated in different parts of a string, removing all instances of duplication). This is vectorized over string and pattern.

### Usage

    str_singleize(string, pattern)

### 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()`.

### Value

A character vector.

### Examples

    str_singleize("abc//def", "/")
    str_singleize("abababcabab", "ab")
    str_singleize(c("abab", "cdcd"), "cd")
    str_singleize(c("abab", "cdcd"), c("ab", "cd"))
