I hope you can help me. I'm trying to put error bars in a xyplot trellis graph (see below). I know there is a function for this, larrows, but for the life of me I can't figure out how to use it. I've been using the default panel function (which is I haven't specified any panel function) and this produces the plot that I like. I've tried defining a panel function based on some of the examples in the panel.* functions in lattice, but without much success. I would appreciate any help that anyone can give me with this problem. I can provide the data as an attached e-mail if needed.
Thanks,
xyplot(log10(Females+1)+log10(BG+1)~Trap.Type|Species,trap.agg,allow.multiple=T,type='b',as.table=T,auto.key=T)
