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?
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.
