grob questions
...und(1:10/11, 2)) > grid.edit("myplot::xaxis::labels", y = unit(-1, "lines")) then > str(myplot$children$xaxis) lists 'at' but not the 'labels'. yet if I do this then the labels are listed: > xx <- xaxisGrob(name = "myX", at = 1:10) > childNames(xx) [1] "major" "ticks" "labels" 1. How do I get to labels in the first case? 2. Is there a better construct than myplot$children$xaxis? Thanks.

placing rectangle behind plot
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
