I see the same thing on an AIX machine with the patched R-release of
yesterday. I've recently noticed this problem when I tried to change
the colortype. For this you have to shutdown all devices, then I got
the error messages. I figured this might be an "AIX" thing at
first...
Possibly related (if not, I'll file separate bug reports):
1) I cannot reset the colortype. When I run out of colors, I used to
be able to just shutdown all devices, then restart with
x11(colortype=....). Now I get:
R> x11()
R> plot(1:100,col=rainbow(100))
Error in plot.xy(xy, type, col = col, pch = pch, cex = cex, bg = bg, lty = lty, :
Error: X11 cannot allocate additional graphics colors.
Consider using X11 with colortype="pseudo.cube" or "gray".
R> dev.off()
null device
1
R> x11(colortype="pseudo.cube")
R> plot(1:100,col=rainbow(100))
Error in plot.xy(xy, type, col = col, pch = pch, cex = cex, bg = bg, lty = lty, :
Error: X11 cannot allocate additional graphics colors.
Consider using X11 with colortype="pseudo.cube" or "gray".
In addition: Warning messages:
1: X11 protocol error: BadAccess (attempt to access private resource denied)
2: X11 protocol error: BadAccess (attempt to access private resource denied)
3: X11 protocol error: BadAccess (attempt to access private resource denied)
R> dev.off()
null device
1
R> x11(colortype="gray")
R> plot(1:100,col=rainbow(100))
Error in plot.xy(xy, type, col = col, pch = pch, cex = cex, bg = bg, lty = lty, :
Error: X11 cannot allocate additional graphics colors.

In addition: Warning messages:

R> dev.off()
null device

2) Plots are not updated if the window is made visible (from being
partially obscured) during a computation before or during the plot.
Let's say my xterm (or emacs window) covers the north-west quadrant
of R's x11 device window. Then:
R> data(iris)
R> pairs(iris[,1:4])
While pairs is drawing, I bring the device window to the front.
All plots that were drawn by pairs will not be redrawn once pairs
is done. So I have to push the device window in the back, then
bring it to the front again to force a redraw/refresh.
This gets really annoying when you have two X11 devices open. If
you bring the inactive one to the front while R is busy plotting on
the active device, the inactive one will not be redrawn/refreshed
once plotting is done. Just white space staring back at you...
