R devel - Aug 2001 - problem in plot(), combining log="y" with type="s" (PR#1078)

I just noticed this behavior of plot().  If you combine: log="y", with
type
="s", specify ylim, AND have plotting points outside of ylim, then the
R
process hangs.
For example:

plot(1:10,seq(0.0001,1,length=10),ylim=c(0.01,1),type="s",log="y")

It will also hang if the original plot() command did not specify ylim, but
a subsequent
lines(x,y,type="s")
has data points outside the plotting limits established by plot.

In Windows 98, [Esc] does not interrupt the loop, but in Irix, ^C does.

I've found this in both:

Thanks for the report.  This is fixed in 1.3.1 (coming soon).

For the record, I'm assuming this is (yet another) example of the bug that
was fixed for bug#997 (bug in CSclipline)
