str_singleize: 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. The string(s) to be purged of duplicates.

pattern

A character vector. Pattern(s) specified like the pattern(s) in the stringr package (e.g. look at stringr::str_locate()). If this has length >1 its length must be the same as that of string.

Value

The string with the duplicates fixed.

Examples

# NOT RUN {
str_singleize("abc//def", "/")
str_singleize("abababcabab", "ab")
str_singleize(c("abab", "cdcd"), "cd")
str_singleize(c("abab", "cdcd"), c("ab", "cd"))
# }
