Find matching indicesSource:
str_subset() returns the indices of
string where there's at least
one match to
pattern. It's a wrapper around
which(str_detect(x, pattern)), and is equivalent to
Input vector. Either a character vector, or something coercible to one.
Pattern to look for.
Match a fixed string (i.e. by comparing only bytes), using
fixed(). This is fast, but approximate. Generally, for matching human text, you'll want
coll()which respects character matching rules for the specified locale.
Match character, word, line and sentence boundaries with
boundary(). An empty pattern, "", is equivalent to
TRUE, return non-matching elements.
