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)
[1] FALSE

and 1 is obviously an integer value.

Obvious?

You must know something I do not, as the protagonist of Zen and the Art of Motorcylce Maintenance would have pointed out.

And if you do then it is not really obvious.

is.double(1)
[1] TRUE

1L _is_ an integer.

is.integer(1L)
[1] TRUE


So this is not a bug. Please see the FAQ for advise on not posting non-bugs.

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

Thanks in advance,

Mauricio
