Short answer: yes, they are.

Long answer: it depends on the precise platform and how your R was compiled, what was on it.

On Mac, they should "just work", though I've heard rumors it is not always true.
On Linux, there are various packages you may need, and once in a while a binary is uploaded which was not compiled with them. One resource might be this ask.sagemath.org question. This ticket may also be of use.
On the xyz.sagenb.org machines, you should be ok. I've used R graphics on them many times.

Edit: Turns out that the poster actually just needed to create a graphics device and turn it off - see this documentation, where this is implicit. Hope this helps someone!

I got the same problem. I just followed: http://ask.sagemath.org/question/192/compiling-r-with-png-support installed all the libraries, compiled the R and r.eval('capabilities("png")') returns true, and r.eval('capabilities("X11")') returns False. When I plot something in R, I get a broken icon (I am running Sage 5.9 via ssh from a remote server).

I got it working. Just adding r.png() at the begining and r.dev_off() at the end of the cell.

Hah! I'm sorry, I'll add this to the answer - this is in fact in the Sage documentation, so I was thinking something much more complicated.
