The nice thing about R is if you don't like something, then get create
your own function (is.Integer?) that does what you want without asking

You can have whatever functions your heart desires and use them
privately and quit bellyaching about a very good software projects.
If you have ever worked in developing software, then you know there
are always "work arounds" to any problem.
That's not the point. Once it is drawn to my attention that
is.integer()
does not do what one would reasonably expect, I can cope with that,
quite easily. I already suggested creating one's own function to do
what one wants (I suggested the name is.WholeNumber() --- is.Integer()
has the advantage of being shorter, but the disadvantage of being more
error-prone; slip on the shift key, and then where are you? :-) )
The point is that is.integer() is a trap, for all but the ultra-
sophisticated.
It invites errors, and is unnecessarily counter-intuitive.
Given that is.integer() exists in its current form, and is not going
to change, it would help if the counter-intertuitive nature of the
function were prominently warned about in the help.
