How can I use your method?
The idea is the same: you need to get your data
into long format with a grouping variable and
then use the 'groups' argument to xyplot.
Here's fake data frame (you should have provided one):
DF - data.frame(y1 = rnorm(30),
y2 = rnorm(30) + 2,
x = rep(1:10, 3),
sites = gl(3, 10, lab=LETTERS[1:3]))
## Use the reshape2 package to melt the data:
## (or use reshape() in base R)
require(reshape2)
DF1 - melt(DF, measure.vars = c('y1', 'y2'),
variable.name = 'grp', value.name = 'y')
## and plot:
require(lattice)
p - xyplot( y ~ x | sites, data = DF1, groups = grp,
col = c(red, blue), type = b)
print(p)
Peter Ehlers
By the way, in this particular case there is a shortcut which does the
reshaping internally:
xyplot(y1 + y2 ~ x | sites, DF, type = b)
Great Felix! this is what I was looking for!
But if y1 and y2 have a different scales? Can I plot, for example y2, on
secondary axis?
Thanks for your help,
Francesco Nutini
sorry for my ignorance!

Something like this?
x - rep(1:10, 2)
y1 - rnorm(10); y2 - rnorm(10) + 2
y - c(y1, y2)
g - gl(2, 10)

Right; thanks for the reminder, Felix. I keep forgetting
about that mainly because I almost always need 'long' data.
