Impaired boxplot functionality - mean instead of median

I'd like to add two comments to Martin's sensible response.

1. I've seen several intro-stats textbooks that define a
boxplot to have whiskers to the extreme data values
and then define Tukey's boxplot as a "modified" boxplot.
I wish authors wouldn't do that.

2. I've also seen boxplots used for sample sizes as small
as -- are you ready for it? -- n = 2!! (Admittedly, only in
plots comparing several groups.) The help page for
stripchart() points out that stripcharts "are a good
alternative to boxplots when sample sizes are small".
My own rule-of-thumb: n > 20 for single boxplots, n > 12
for multiple boxplots.

Woul've it make sense to have an option to replace boxes with dotplots
for only those groups with number of observations lesser tahn nmin=20 (say)
