Thank you, Bert. The help page doesn't have a usage example and I
can't seem to find one via google. Do you, or anyone else, have
sample code?
It did not seem particularly daring or complex when I tried this
(which does appear to produce what was requested):
tmp <- data.frame(var1 = c(rnorm(1000), rnorm(1000, 1, 1)), var2 = gl(2,
1000))
densityplot(~ var1|var2, tmp,
type = c('g', 'l'),
layout = c(1,2),
panel = function(x, ...){
panel.densityplot(x, ...)
panel.abline(v = c(0,1)
[ panel.number() ])
}
)

?panel.number
This tells you what panel you're in and you can use that to determine
which line to draw.

But mot
exactly what I think I need. Suppose I have a datafile such as tmp.
tmp <- data.frame(var1 = c(rnorm(1000), rnorm(1000, 1, 1)), var2 =
gl(2,
1000))
I'd like a plot similar to the one below, but with an abline of
v=0 in the
lower panel and v=1 in the upper panel. Code below creates two
lines in each
panel, not quite sure how to separate them by panel.
densityplot(~ var1|var2, tmp,
type = c('g', 'l'),
layout = c(1,2),
panel =
function(x, ...){
panel.densityplot(x, ...)
panel.abline(v = c(0,1))
}
)
Thank you
Harold
