str_after_nth {filesstrings}

R Documentation

Text before or after nth occurrence of pattern.

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 nth 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.
