has_handler_args

A function that is a candidate for being a handler

This makes sure that a given function doesn't require more than one argument to be passed into it, and takes in at least one argument (which is what a <a rd-options="base:conditions" href="/link/handler?package=catchr&version=0.2.31&to=base%3Aconditions" data-mini-rdoc="base:conditions::handler">handler</a> needs).

R has a unique way of dealing with warnings, errors, messages,
and other conditions, but it can often be troublesome to users coming
from different programming backgrounds. The purpose of this package is
to provide flexible and useful tools for handling R conditions with
less hassle. In order to lower the barrier of entry, keep code clean
and readable, and reduce the amount of typing required, `catchr` uses
a very simple domain-specific language that simplifies things on the
front-end.
This package aims to maintain a continuous learning curve that lets new
users jump straight in to condition-handling, while simultaneously
offering depth and complexity for more advanced users.
