This is a very simple function that seems not to be working, according to the
definition given by '?is.integer'.

I checked in the Bug Tracking page at http://bugs.R-project.org/, but I didn't
find any related message.

The possible problem is:

> is.integer(1)

and 1 is obviously an integer value.

I would really appreciate if you could clarify if this is really a bug or not.

Thanks in advance,
