John,

Thank you for bringing this to my attention. I was out of town all day
on a business trip and will look at this issue further with fresh eyes
in the morning. I'll get an update to Greg as soon as I have a chance
to incorporate a fix.  I also have some pending updates for
barplot2(), so I will coordinate the updates with Greg to conserve his
time.

Best regards,

Marc Schwartz
