I'm having difficulty getting plot to work with type="n", when either the x or y variables is a factor.
For example, x <- 1:10 y <- 1:10 plot(x, as.factor(y), type="n") plot(as.factor(x),y, type="n") plot(y ~ as.factor(x), type="n") produce plots with data plotted, whereas plot(x,y, type="n") plot(y ~ x, type = "n") produce the expected dataless plots I am running R1.8.1 on Windows (xp), with the windows graphics device. I have a friend who has tried this on a Mac (OS 10.3.3. with quartz() and x11() devices) and gets erratic behavior, i.e. sometimes plots works as expected, and sometimes not. Does anyone have any clues on this? Thanks in advance, Aries Arditi, Ph.D. Senior Fellow in Vision Science Arlene R.
