To dear Dr Sarkar and anyone that knows about Lattice package, I make 4 graphs by Lattice package. Each of the graphs has two time series. All the series are plotted in plain lines by default, and I would like one series to be in plain line and the other to be in dotted line in each graph. How can I modify the command of xyplot in the following line to achieve this? It seems that "key" or "auto.key" parameters are needed, but I don't know how to do it. Thank you very much!
require(graphics) library(lattice) data1<-read.csv(file="G_Results_3FX1.csv", header=TRUE) xts<-ts(data1[,2:9],frequency = 4, start = c(1983, 1)) xyplot(xts, screen=list("a","a","b","b","c","c","d","d"), layout=c(2,2), scales=list(x="same",y="same")) Miao [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
