R-helpers:
I need a quick help with the following graph (I'm a lattice newbie):
require("lattice")
npp=1:5
names(npp)=c("A","B","C","D","E")
barchart(npp,origin=0,box.width=1)
# What I want to do, is add a single vertical line positioned at x = 2 that
lays over the bars (say, using a dotted line). How do I go about doing
this?
