...ly let me create that many colours? 2) if not, how do I test if there is not, and implement gray instead of colours? This function and package works on windows, and it works with less colours. I guess I could try and trap the error, and if I can, go back and re-run the function with "options(X11colortype="gray")" but I'd prefer something more elegant... What I'm looking for is some test where I can say "If you're going to fail, X11colortype='gray', else X11colortype='true'". Possible? Many thanks Mick The information contained in this message...

However, > png("toto.png") > image(matrix(rnorm(10000), 100, 100)) > dev.off() works fine. I tried: > options(X11colortype = "pseudo.cube") > png("toto.png") > image(matrix(rnorm(10000), 100, 100)) > dev.off() But, here again, R is blocked. I tried to replace dev.off() by graphics.off(), but this does not resolve the problem. The problem does not occurs when the function X11() is used i...

I have made some modifications to the X11 graphics driver so that it is more flexible about its use of colors. I have added a new parameter to the X11/x11 function which controls this. The parameter is currently called "colormodel" and works as follows: colormodel = 0 Monochrome graphics colormodel = 1 Grayscale (256 shades) colormodel = 2 Pseudocolor1 colormodel = 3

I have been receiving complaints that my libraries no longer give reasonable graphics with R0.90. I have been replying that I have not changed anything. Among my travels (presently in Umea), I have finally had a chance to take a look. The best way to describe the current default graphics is HORRIBLY UGLY. The R core member who made those changes should buy glasses to see the screen better instead

...le graphics in an example just fly by, unless the PD> user sets the parameter. yes, definitely a reasonable feature request! -- see below BUT, for a first "quick fix" : Why not change X11's argument pointsize = 12 to pointsize = .Options$X11pointsize (we already have X11colortype !). Now back to the feature request: Do we want par.defaults() for this? It would have the same arguments as par() plus additional device = .Options$device with further possibility device = "all" i.e., by default, par.defaults() would set things only for the default device,...
