There is a grid.roundrect(), in case you are working in that
alternative universe.
p.s. Is it feasible to mix grid with traditional graphics? Your Ch. 6
begins, "This chapter is useful for drawing ... from scratch, and for
adding output to plots created by lattice and ggplot2." However, I
understand that grid produces graphics object or grobs, which are
"printed" to be viewed. Thanks. Spencer
Take a look at the 'gridBase' package (Chapter 19 of R Graphics 2e).

Hi, Paul:
Is there an easy way to specify the roundrect arguments in
standard user coordinates? "plot(7:8); grid.roundrect(.6, .4, .4, .2,
name='rr')" gave me a rectangle occupying roughly 50% of the horizontal
space and 30% of the vertical space in the plot region [not 40% and 20%
as I might naively expect], centered at roughly (1.6, 7.4).
I found grid.roundrect mentioned on p. 179 of the second edition
of our "R Graphics". I'll try reading that first part of your chapter 6
to see if that produces sufficient enlightenment. I failed to achieve
sufficient understanding of grid from your first edition.
Thanks,
Spencer

Is there a function for creating a box with rounded corners?
I can write one, but I thought I'd ask first.
Thanks,
