There are some things that I wish were easier with the stringr or stringi packages. The foremost of these is the extraction of numbers from strings. stringr makes you figure out the regex for yourself; strex takes care of this for you. There are many more useful functionalities in strex. In particular, there’s a match_arg() function which is more flexible than the base match.arg(). Contributions to this package are encouraged: it is intended as a miscellany of string manipulation functions which cannot be found in stringi or stringr.

The github repo of strex is at https://github.com/rorynolan/strex.
