Thanks all for following up. I'll consider the bug "filed." I should note for the record that if 'col="red"' is replaced in my code by 'col.main="red"' the x axis is still made red.
I'll use the workaround for now (for which thanks). Even with little things like this, plotting from the command line in R is orders better than dragging a bunch of frames around an Excel window.
