[R] x11 and pseudo-color
for some reason the 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 capabilities from within R in order to being able to open the X11() displays always (for true color as well as for 8 bit) with the correct colortype setting from within a function? regards, joerg __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

R does try to determine the capabilities of the X11 server. I think what may be happening is that your display is being correctly identified as pseudocolor, but R has two strategies for handling pseudocolor, pseudo and pseudo.cube and it uses pseudo by default (see ?x11). If you use more than 256 colours under this scheme you will run out of colours. question 2: is there a possibility to query the color capabilities from within R in order to being able to open the X11() displays always (for true color as well as for 8 bit) with the correct colortype setting from within a function? Not that I know of.
