          <div>I am running iPython remotely and I don't have X11 setup.
            For some <br>
            reason, RMagic, even with simple code, is trying to present
            a PNG <br>
            through X11, and failing since there is no X11.<br>
            <br>
            I tried %gui to turn of any GUI integration. When I enter
            "%R b &lt;- <br>
            c(1,2,3,4)" I get a RRuntimeError:<br>
            <br>
            RRuntimeError: Error in png("/tmp/tmpwGLwWm/Rplots%03d.png",
            ) : X11 is <br>
            not available<br>
            <br>
            Why would RMagic be trying to produce a png?<br>
            <br>
            I tried this in the web notebook as well and got the same
            error.<br>
