I am trying to create a lattice plot and would like to later, i.e. after the plot is drawn, add a grey rectangle behind a portion of it. The following works except that the rectrangle is on top of and obscures a portion of the chart. I also tried adding col = "transparent" to the gpar list but that did not help -- I am on windows and perhaps the windows device does not support transparency? At any rate, how can I place the rectangle behind the plotted points without drawing the rectangle first?
library(lattice) library(grid) trellis.unfocus() x <- 1:10 xyplot(x ~ x | gl(2,1), layout = 1:2) trellis.focus("panel", 1, 1) grid.rect(w = .5, gp = gpar(fill = "light grey")) trellis.unfocus() ______________________________________________ R-help@stat.math.ethz.ch 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.
