Running Graphics[RegularPolygon] in Mathematica on a non RPi works as expected (running v. 10.4). But when I try that under the RPi release, I get the message that RegularPolygon is not a primitive or directive. Toying around with 2D,3D or << `Graphics won't work either. Any idea where to adjust the syntax to make it work?
Yes, I had a good connection. If I run $Version it tells me I'm running 10.0.0. Is that the most recent Pi version available? In doing an update, I'm told I'm using the most recent version of Mathematica for the RPi. Which version are you running?
