Logical operations on brobs are not supported
The S4 group generic “Logic” appeared in R-2.4.0-patched.
Carrying out logical operations in this group will call
.Brob.logic(), which reports an error.
!”, is not part of this group: attempting to
negate a brob will not activate
.Brob.logic(); an “invalid
argument type” error is given instead.
