You can retrieve the undelying grid layout and show it using library(grid) grid.show.layout(lattice:::lattice.getStatus("layout.details")$page.layout) which is close to what you are describing. Otherwise, there's no easy way to insert polygons in these areas that I know of. You could try setting negative padding values to see what they do. -Deepayan > Any advise on how to improve this code would be greatly appreciated. > > Sebastien > > ####################### > library(lattice) > foo <- > data.frame(x=rep(seq(10),9),y=rep(seq(10),9),z=rep(0,90),id=rep(seq(9),each=10)) > plot1 <- xyplot(y+z~x|id, > data=foo, > type=c("p","l"), > distribute.type = TRUE, > main="This is a test", > sub="Subtitle", > auto.key=T) > trellis.device(pdf, file = "trellis_par_test.pdf", > paper="letter", > #family="Courier", > theme = list(fontsize = list(text = 10, points = 10))) > trellis.par.set(layout.widths =list(left.padding=0, > right.padding=0), > layout.heights=list(top.padding =1, > main.key.padding =1, > axis.xlab.padding=1, > key.sub.padding =1, > bottom.padding =1), > axis.components=list(top=list(tck=1, > pad1=1, > pad2=1), right=list(tck=1, > pad1=1, > pad2=1))) print(plot1) > dev.off() > ########################### > > > > -- > *Sebastien Bihorel, PharmD, PhD* > PKPD Scientist > Cognigen Corp > Email: sebastien.biho...@cognigencorp.com > <mailto:sebastien.biho...@cognigencorp.com> > Phone: (716) 633-3463 ext. 323 > > ______________________________________________ > 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.
