Hi Mark,
# With auto.key you can specify in a list what kind of graphical output you
would like to see in your legend, e.g.
require(lattice)
mydata <- data.frame(x=1:4,y=1:4, g=c("a","a","b","b"))
xyplot(y~x, groups=g, data=mydata,
t="l", auto.key=list(lines=TRUE, points=FALSE))
# See as well the documentation for auto.key and key under ?xyplot
# As an alternative you might want to use simpleKey
?simpleKey
xyplot(y~x, groups=g,data=mydata, t="l",
key=simpleKey(text=levels(mydata$g),lines=TRUE, points=FALSE))
Regards,
Markus

Subject: [R] how to make auto.key to produce a legend that uses line pattern
(rather than data point) as labels?
Hi!
I am working on a line graph under xyplot. what command should I feed
to auto.key so that it uses the line pattern of series as labels?
Also where can I find doc about all options that I can feed to auto.key?
Thanks!
Mark
