Hi, does anyone know how to make pairs of boxplots? E.g. 5 pairs of boxes. I figured a not very elegant way, by inserting a dummy NA field to the list where the data is given. So, where I have the dummy I got more distance between boxes, as a result it looks like groups. But I am having problems with putting the names under the groups, and the thick marks. Any better idea? Thanks, Kati ___ Katalin Csillery Division of Biological Sciences University of Montana, Missoula MT 59801 Phone: 406 243 6106, E-mail: csillery at selway.umt.edu ----------------------------------------------------

Use the 'add' and 'at' arguments to boxplot(). Better yet, look at the last example in ?boxplot For the labels, use the midpoints of the pairs of 'at' values for mtext(). See ?mtext for more details. Regards, Marc Schwartz
