The base package is special as it contains the primitives and
these do not have definitions available at code level. We provide
equivalent closures in environments
.GenericArgsEnv in the base package that are used
for various purposes:
undoc("base") checks that all the
primitives that are not language constructs are prototyped in those
environments and no others are.
An object of class
"undoc" which is a list of character vectors
containing the names of the undocumented objects split according to
There is a
