str_singleize {strex}

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.
