Hi Uwe, I am aware of the "legend" option in xyplot, but I can't figure out how to make it work. In particular, I do not understand how to use "legend" along with the "key" argument. For my example, I would like to have a legend box inside the plotting frame to indicate the 3 different smoothed curves. Can someone give me a simple example or show how to do this for my example?
Thanks very much, Ravi. > -----Original Message----- > From: Uwe Ligges [mailto:[EMAIL PROTECTED] > Sent: Tuesday, January 17, 2006 3:08 AM > To: Ravi Varadhan > Cc: [email protected] > Subject: Re: [R] Legends in xyplot > > See ?xyplot and its argument "legend". > > Uwe Ligges > > > > > Ravi Varadhan wrote: > > > Hi, > > > > > > > > How can I add legends in the "xyplot" function, in the "lattice" > library? > > Here is a simulation example: > > > > > > > > x <- runif(90) > > > > z <- sample(1:3, 90, rep=T) > > > > y <- rnorm(90, mean = x^2 + z, sd=1) > > > > > > > > library(lattice) > > > > trellis.par.set(col.whitebg()) > > > > xyplot(y ~x, groups=as.factor(z), type = c('p', 'smooth'), span = .67) > > > > > > > > Thanks in advance, > > > > Ravi. > > > > > > > > > > [[alternative HTML version deleted]] > > > > ______________________________________________ > > [email protected] mailing list > > https://stat.ethz.ch/mailman/listinfo/r-help > > PLEASE do read the posting guide! http://www.R-project.org/posting- > guide.html ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
