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 
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.
