I have a question regarding plotting in R. If I go to Notebook (change to r from the drop down menu) and type
x<-c(1,2,3) plot(x) I get a strange error message: Error in png(): X11 is not available I have made the start scripts available with install_scripts('/usr/bin'). If I issue those commands in the R console then nothing happens (without error message). if I issue capabilities() I get the following results: jpeg (FALSE ) png (FALSE) tiff (FALSE ) tcltk (FALSE) X11 (FALSE) aqua (FALSE) http/ftp (TRUE ) sockets (TRUE ) libxml (TRUE ) fifo (TRUE) cledit (TRUE ) iconv (TRUE) NLS (TRUE) profmem (FALSE ) cairo (FALSE) So R thinks I have no X11 system ( I have, xorg with JWM and GTK) and no support for graphic files (I have libpng.so installed in /usr/lib , and I also find it in the sage tree, so probably sage has its own version) I had googled alot and found there were some issues with the R- plotting interface, but as far as I understood this should be fixed, so basically it should be possible to plot from R. This is in the live CD version which uses Puppy Linux (has Ubuntu Binaries). I installed sage (4.6) directly from the Ubuntu binaries (passed sage -testall without errors). Could this be fixed easily (maybe some symlinks?). Or is there a chance for a fix if I compile sage on the system from source? I also tried the current vmimage on a windows host and it gives the same for r.capabilities(). I got feedback from people who are very interested in the sage package but mainly want to use some components in a "classical" way (e.g. Rcmdr with R) - Do you think this is possible at all? many thanks for any hint on this 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
