I have a toy example given here: par(fig=c(0,1,0,0.05)) par(mar=c(0,0,0,0)) par(plt=c(0,1,0,1)) par(oma=c(0,0,0,0)) par(ann=F) plot(c(0,1),c(0,1),type='n',xlab='',ylab='',main='') rect(0,0,1,1,col='gray75') What parameter am I missing to make the gray rectangle use the entire figure region? I am trying to build a plot from pieces, but there is a little bit of margin left by the code above that prohibits the pieces from fitting together perfectly. Thanks, Sean

Dear expeRts, I am not sure if I found a bug... I would like to create a function that itself creates a lattice plot without colors. Following http://www.mail-archive.com/r-help at r-project.org/msg64699.html I use trellis.device() to set the colors to FALSE. Whenever I call the minimal example below *with* trellis.device(), Quartz opens a window (I am working on a MAC), which it shouldn't,

...p ### of them. You can grab shades of gray like "gray30" or such. ### I'll just specify 4 colors I know will work. I prefer ### the light gray colors because they can be written over. mycols <- c("lightgray","gray70","gray80","gray90","gray75") barplot(x, names=mynames, las=2, col=mycols) legend(2,20,legend=c("A","B","C","D"),fill=mycols) ### Still, I don't like the solid shades so much. ### fill up the bars with angled lines. ### density determines number of lines inside the bar. myd...
