R devel - Mar 2009 - logical comparison of functions (PR#13588)

Submission from: (NULL) (164.67.71.215)


When I try to say if (method==f), where f is a function, it says that the
comparison is only possible for list and atomic types.  I tried saying if
(method!=f), and it gave the same error message.  Would it be possible to repair
it say that == and != comparisons would be possible for functions?

This is not a bug.  Please don't report things as bugs when they aren't.
  "==" and "!=" are for atomic vectors, as documented.

Use identical() for more general comparisons, as documented on the man 
page for ==.
