Paul Murell's article "What's in a Name" in The R Journal Vol 4/2 gives an interesting example of editing a stacked barplot of the barley data. Using the method described in that article, it's easy to do something along the lines of
grid.edit("plot_01.border.strip.1", grep=TRUE, global=TRUE, gp=gpar(col = "red")) That changes more than I'd like to change. I'd like to change only the bottom line of the rectangle. How would I overwrite the unwanted red lines along the lines of what box() would do with base graphics?
