...ork. e.g. with(gdsgraph, gdsbox(BReT3T5T)) produced an error that gds3level was not found but if I try with(gdsgraph, boxplot(BReT3T5T~gds3lev)) it works fine. Similar problems occurred when I tried to use data = What am I missing? Thanks Peter Peter L. Flom, PhD Brainscope, Inc. 212 263 7863 (MTW) 917 488 7176 (ThF) [[alternative HTML version deleted]]

...n. The only thing that changes is BReP3O1T. The problem is that sometimes this occurs as text (e.g. in ylab and main) sometimes after a $ (e.g. in the first two assigment statements), and sometimes it refers to the values (e.g. in ymin and ymax) Any help appreciated.
