I understand the reasoning and that it is impossible to have every feature working out of the box on every machine. In case of plotting in R I think this is one of the finest parts of that package, so its a shame it is problematic. I was always ignorant of sage -testall --optional! ;-) I always thought I am very thouroughgoing with my sage -testall after each installation. Hm, does R need the Xorg - dev headers to work properly? Thats the only reason I can imagine it is not feasable to build that into a standard binary (X and linpng should be there in 99.99 % of Ubuntu installs). I am not sure about it, because I have tested an R package without those headers installed, and demo(graphics) worked fine. The VM is a different story, but it should be possible to build one where plotting is working. emil -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
