[R] boxplot with text and symbols on x

[Greg Snow]

An alternative way to draw the symbols (or some approximation of them) is to use the my.symbols function from the TeachingDemos package along with ms.male and ms.female (or your improvement of these, also from the TeachingDemos package).  See the 4th example from ?ms.male (or ?ms.female).

Hope this helps,
