[R] difficulies with boxplot

[Nina Lieske]

Dear list,

sorry for bothering you with a probably simple question... I searched
the archive but couldn't find the right answer.

I have computed  upper and lower bounds of  a region and would like to
plot them in a boxplot. My problem is now to get the two boxplots in the
same graphic so that the boxplot of the upper bounds is directly on top
of the boxplot of the lower bounds. The reason I don't want to have them
next to each other is that I have another  "grouping" variable. I tried
"add" but didn't succeed.

I'm using R 0.64.2 on Windows NT.

Thanks for your help,
Nina Lieske
