vname


Tries to heuristically determine the variable name of <code>x</code> in the parent frame
with a combination of <code><a rd-options="base" href="/link/deparse?package=checkmate&version=1.8.1&to=base" data-mini-rdoc="base::deparse">deparse</a></code> and <code><a rd-options="base" href="/link/substitute?package=checkmate&version=1.8.1&to=base" data-mini-rdoc="base::substitute">substitute</a></code>.
Used for checkmate's error messages.


Tests and assertions to perform frequent argument checks. A
substantial part of the package was written in C to minimize any worries
about execution time overhead.
