str_detect_approx(string, pattern, ...)

str_which_approx(string, pattern, ...)

str_subset_approx(string, pattern, ...)

Arguments

string	Input vector. Either a character vector, or something coearcible to one.
pattern	Pattern to look for.
...	see the documentation for agrep() for other arguments passed on to agrep() or agrepl()
