It's easier if you include the legend in the call (so that print.trellis can do the layout management); e.g., see http://lmdvr.r-forge.r-project.org/figures/figures.html?chapter=05;figure=05_06;theme=stdBW;code=right > 2) How do I put a label on the color key? > I would like to give the color key a label as the label 'x' for the y- > axis, so it should be vertically printed and located to the right of > the color key.

You can still define your own legend, of course. -Deepayan > > Thanks very much. > > Marius > > library(lattice) > library(grid) > x=c(1,2,3) > colorseq=c(0.2,0.5,0.8) > mycolors=gray(colorseq) > #trellis.device(postscript,horizontal=F,onefile=F,file="~/testplot.ps") > xyplot(x~x,col=mycolors,aspect=1) > draw.colorkey(key=list(at=seq(1,3,length=4),col=mycolors,text=list(c > ("test"))),draw=TRUE,vp=viewport(x=1,y=0.6,height=0.8)) > #dev.off() > > ______________________________________________ > 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. > ______________________________________________ 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.
