palette() can hang and fail due to X11
...my R was interactive or not, or if my Linux, ssh, and screen
environment had X-Windows properly set up or not. It Just Worked.
However, now in R 3.1.0 Patched (2014-04-15 r65398, on Linux),
depending on whether I have a good X-Windows connection or not it can
fail like so:
Error in .External2(C_X11, d$display, d$width, d$height, d$pointsize, :
unable to start device X11
Simply wrapping the palette() call in try() of course helps keep that
error from breaking the rest of my R start up. However, occasionally
the call to palette() will hang for perhaps a minute, unexpectedly
locking up...

Shouldn't grDevices::quartz() give an error instead of a warning when not available?
Compare:
> quartz(); cat("Should this have generated an error instead?\n")
Warning message:
In quartz() : Quartz device is not available on this platform
Should this have generated an error instead?
to:
> x11()
Error in .External2(C_X11, d$display, d$width, d$height, d$pointsize, :
unable to start device X11cairo
In addition: Warning message:
In x11() : unable to open connection to X11 display ''
Wouldn't it make sense that a failed call to quartz() would give an
error instead?

capabilities("X11"): Force refresh from within R? (... and minor documentation issue)
...out restarting R
such that it reflects the enabling/disabling of X11?
BACKGROUND:
If I launch R with X11 server disabled (e.g. ssh -X / ssh -Y to remote
Linux but forgot to enable Xming on local Windows), then I get:
> capabilities("X11")
X11
FALSE
> x11()
Error in .External2(C_X11, d$display, d$width, d$height, d$pointsize, :
unable to start device X11cairo
In addition: Warning message:
In x11() : unable to open connection to X11 display ''
So far so good. However, if I then enable the X11 server (e.g. start
Xming on Windows), I still get:
