R help - Mar 2014 - Selecting numbers not divisible by 3

Hi,
here's my code

X <- 1:100

I want to select number divisible by 3 out of them how can I select it?

( I tried following
X <- 1:100
DIV <- Y - > X/3

But I am getting whole number and number with fractions. WHole intgers are
my number of interest from original X. How can I traceback to number
divisbile by 3. ?)

Thanks

Kind Regards,
Prabhakar
