Hi Marcio,
it's not a bug, it's a well-documented feature. In the S language, numeric literals are floating point by default.

Best wishes Wolfgang

Hello!
I'm not sure if is it a BUG or not... I'm using R 1.9.0, and I used the command below:
is.integer(9)
[1] FALSE
R manual contains this words about the is.integer() function:
"is.integer returns TRUE or FALSE depending on whether its argument is of integer type or not."
What's the problem? Am I wrong about the BUG report?
Thank you very much.
