I experienced the following problem with R 1.3.0 which is probably a bug. The program hangs-up if 1.) a coordinate of segments is outside the ploting region and 2.) the option log="x" is used. ## ## works fine ## plot(1,1, xlim=c(0.5, 2), ylim=c(0.5, 2)) segments(0.5 , 1.2, 1, 0.6) segments(0.25, 1.2, 1, 0.6) segments(1 , 1.2, 1, 0.6) ## ## hang-up ## plot(1,1, xlim=c(0.5, 2),

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

I have done a little bit of poking around at the bug that I reported earlier (steep slopes and lines from far outside the plot range doing funny things), and have tracked it down to the fact that, as noted in the Unix man page, XDrawLine[s] doesn't like coordinates that are outside of the range of (-32767,32767). Now the question is, what to do about this? A quick "fix" (not a fix
