Extra String Manipulation Functions
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' and 'stringi' make you figure out the regular expression for yourself; 'strex' takes care of this for you. There are many other handy functionalities in 'strex'. Contributions to this package are encouraged: it is intended as a miscellany of string manipulation functions that cannot be found in 'stringi' or 'stringr'.

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().
