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'.
Readme
strex 
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 lets you figure this 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.
