str_which: Find positions of strings matching a pattern

In stringstatic: Dependency-Free String Operations

Find positions of strings matching a pattern

Description

Dependency-free drop-in alternative for stringr::str_which().

Usage

str_which(string, pattern, negate = FALSE)

Arguments

string	Input vector. Either a character vector, or something coercible to one.
pattern	Pattern to look for. The default interpretation is a regular expression, as described in base::regex. Control options with regex(). Match a fixed string (i.e. by comparing only bytes), using fixed(). This is fast, but approximate.
negate	If TRUE, return non-matching elements.

Value

An integer vector.
