I'm very new to R so please forgive any lack of knowledge. I am doing a course which needed the package rgl and managed to work out (finally) that I needed to install XQuartz - which I have done. It is working but I can't get the plots to show in colour - they are only in black and white. Does anyone know what I'm doing wrong / how to fix it? I've tried looking at the XQuartz documentation but can't work it out.
Thanks!
