[R] Plot ``freezes''.

[Rolf Turner]

In an elderly version of ``plotSymbols'' (now in the cwhmisc package) that
I had lying around, there was the example

plot(1:10,xlab="\374")

which the comments said would give a u-umlaut as the x-axis label.

When I execute this plot

	(a) I get no x-axis label at all, and

	(b) the plot ``freezes'' in that further plotting commands
	(e.g. plot(runif(42))) produce no results.  The plot window (X11)
	remains as it was after the ``plot(1:10,xlab="\374")'' command.
	No error message is given, but no new plot is produced.

If I do dev.off(), then normal plotting recommences.  Can anyone explain
to me what is going on here?  My session info is given below.  I run R
from the command line, from a terminal window.

	cheers,

		Rolf Turner
