Dear list.
I have three histograms and I want to add a vertical abline in a
different
place in each plot. The next example will plot a vertical line at
x=5.5 in
the three plots:
rnorm(100,5,3) -> A
rnorm(100,7,3) -> B
rnorm(100,4,1) -> C
rep(c("A","B","C"),each=100) -> grp
data.frame(G=grp,D=c(A,B,C)) -> data
histogram(~ D | G, data=data, layout=c(3,1), nint=50,
panel=function(x,...){
panel.histogram(x,...)
panel.abline(v=5.5)
})
But I'd like to plot a vertical line at 5.5 in plot A, 6.5 in plot B
and
4.5 in plot C. How can I do that?
histogram(~ D | G, data=data, layout=c(3,1), nint=50,
panel=function(x,subscripts,groups,...){
panel.histogram(x,...)
panel.abline(v=c(5.5, 6.5, 4.5)[packet.number()])
})
Thanks in advance..
