match_arg

This function matches function arguments and is a modified version of
<code><a href="/link/match.arg?package=oeli&version=0.5.2" data-mini-rdoc="oeli::match.arg">match.arg</a></code>.

Some general helper functions that I and maybe others find useful
when developing data science software. Functionality includes argument
validation, density calculation, sampling, matrix printing, user
interaction, storage helpers and more. The vignettes illustrate use cases.
