Description

See strex::str_after_nth().

Usage

str_after_nth(strings, pattern, n)
str_after_first(strings, pattern)
str_after_last(strings, pattern)
str_before_nth(strings, pattern, n)
str_before_first(strings, pattern)
str_before_last(strings, pattern)

Arguments

strings

A character vector.

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.

n

A natural number to identify the \(n\)th occurrence (defaults to first (n = 1)). This can be negatively indexed, so if you wish to select the last occurrence, you need n = -1, for the second-last, you need n = -2 and so on.
