Dear R-Developers, on the help page for gpar() is the following paragraph: "Specifying the value NULL for a parameter is the same as not specifying any value for that parameter, except for col and fill, where NULL indicates not to draw a border or not to fill an area (respectively)." The mentioned exception for col and fill does not hold. Actually what is said in the section "Color Specification" on the help page for par() is true also for gpar(): "transparent" and NA specify transparency respectively no drawing. To verify this: grid.newpage() grid.rect(width=.5, height=.5) grid.rect(width=.25, height=.25, gp=gpar(col=NULL)) # draws the box despite col=NULL grid.rect(width=.125, height=.125, gp=gpar(col=NA, fill=2)) # does not draw the box regards, Tom ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
