R magic for ipython notebook runtime error turning

I loved the R magic in ipython notebook. I had to switch to a new server and heard that a huge headache can be taken out by installing everything through anaconda. However, R magic doesn't seem to work, which is half the reason I use ipython notebook.

After installing anaconda, I open a notebook and simply type the following.

%load_ext rmagic
%%R
print("hi")

This produces a Runtime error I can't get to the bottom of:

RRuntimeError: Error in dev.off() : cannot shut down device 1 (the null device)

I restart my server to assure that the only R instance running is this one. Rpy2 works, as I can print out plots using this library, but the R magic always produces this RunTimeError.

Any help?

(I'm not sure if I should post this on SO or another exchange, but based on what answers I get, I will adapt)

I'm not sure if this advice from another thread helps, but seems like newer versions of rpy2 do not use %load_ext rmagic anymore. You might want to try %load_ext rpy2.ipython.
