Hi, I occasionally run out of color in my X11 terminal. At this point, R will issue this error message: Error: X11 cannot allocate additional graphics colors. Consider using colortype="pseudo.cube" or "gray". An immediate x11(colortype="pseudo.cube") doesn't work as the colortype seems to be shared among the different x11 plotting windows. So I have to close all windows first, then I can open an x11 device with the colortype "pseudo.cube&...

...her technique is to connect in shh -X to execute my R script. With the connection ssh -X, my R script is well executed. BUT when I use Xvfb, some graphics are created but an error occured and stop the script. here the error : " X11 cannot allocate additional graphics colors. Consider using colortype="pseudo.cube" or "gray" " There is obviously a problem witth xvfb but I can't not resolve it please help me! Thank you Gael Even

One can use a model which differs from the X11 visual class, but the default class and d...

...following message seems not to have reached the list in the first try, at least I can't find it. my apologies if this is my fault: we are running R under Solaris with SunRay Terminals, which are set to 8 bit color to comply with some other software. In this configuration, X11() opens with colortype=true, i.e., it is not recognized that actually the display is only 8 bit. This leads to error messages (advising to use 'pseudo.cube'). question 1: is X11() supposed to recognize the actual color capabilities? i.e. is this a bug? question 2: is there a possibility to query the color cap...

I'm trying to use the lattice package (and have run into the message before) where I will get the following when trying to plot.... Error in clearpage() : Error: X11 cannot allocate additional graphics colors. Consider using X11 with colortype="pseudo.cube" or "gray". What do I need to do to get rid of this so that I can use the graphics libraries to their fullest potential. Currently, I can't get lattice() to work. Thanks, Jeff. Jeff D.

Does it seem that X windows has a problem with "gray"? Can the default color used by abline() be changed to something other than gray? Or is it caused by incomplete R installation? Thanks for the help! Deling ____________...
