Warning messages:
1: X11 protocol error: BadAccess (attempt to access private resource denied)
2: X11 protocol error: BadAccess (attempt to access private resource denied)
This only happens if all x11 devices are shut down, so the X11 connection
is restarted. We had problems with this when the event handlers
were changed prior to 1.3.0, and it looks as if the logic is still
incorrect.
As far as I can see subsequent plots are correct.
Carrying on:
dev.off()
null device
1
x11()
plot.new()
Warning message:
X11 protocol error: BadAccess (attempt to access private resource denied)
(only one error this time).
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

R> x11(colortype="pseudo.cube")

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...
