In-Reply-To: <OF64BAAB51.93CEFB4D-ON852569DE.004CB60E at rtp.epa.gov> This is more a linux question, but I have asked in some Linux conferences with no success. I am running 1.2.1 in Mandrake 7.2.Trying to run the graphics demo produces axes, but no lines and I get an error message: error in abline (h=0, col=gray(0,9))Error:X11 cannot allocate additional graphics colors consider using x11 with colortype = "pseudo.color" or "gray" I am completely new to R and Linux and I am not sure how to fix this, I am also not sure on how fixing this will affect other program such as Grass which seems to have no problems drawing different coloured lines. Can any one advise me how I fix this? It was installed with the Mandrake RPM, and I did think of installing 1.2.2 to see if that helped, but the Mandrake RPM isn't on Cran, there is a readme, but no binary.

Two ways out: a) I think this only happens with 256-color (8bit) X servers. Set up your X server for 16 bit color depth or better. b) remove application that use many colors. The background image or Netscape are likely culprits, but also the smoothly colored little Gnome icons are troublesome. KDE might be better in this regard according to what I've gathered. Also, you might try taking the hint in that error message, e.g.: c) x11(colortype="gray");demo(graphics) -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.

In-Reply-To: <x2zof2gzxk.fsf at blueberry.kubism.ku.dk> Peter, Many thanks for this, I had inadvertently set the colours to 8 bit because of the resolution I had chosen. Changing this to 800x600 allowed 16 bit colour and R is now drawing graphs.
