R help - Apr 2009 - help on bwplot function

Dear all:

I am using R function bwplot to plot box plots. I would like to change some
parameters of the typical box plots. For example, I would like to try different
types of whisker lines. I can use whiskerline=x in boxplot function but not in
bwplot function. Could you tell me how I can do it in the latter?

Thanks a lot for your help.

For a detailed documentation of bwplot, check panel.bwplot. By typing

panel.bwplot 

without the (), you get the code, and you will notice some lines at the
top that could give you a hint where to tweak some more details.

   box.dot <- trellis.par.get("box.dot")
    box.rectangle <- trellis.par.get("box.rectangle")
    box.umbrella <- trellis.par.get("box.umbrella")
    plot.symbol <- trellis.par.get("plot.symbol")
