R help - Nov 2011 - newbie's question : xyplot legend with a white background

Hello,

Sorry in advance for adding a silly question on this forum but I haven't
found the right keywords to find a solution to this basic problem.
I'm just looking a way to have a white background behind the legend to hide
the grid.

Thanks in advance.


The silly example for my silly question: 

xyplot(1~1,
       panel = function(x,y, ...) {
           panel.xyplot(x,y)
		   panel.abline(v=seq(0,1.4,by=0.1))
		   panel.abline(h=seq(0,1.4,by=0.1))
		 }
,key=list(x=0.2, y=0.88,
points=list(col=c("red","green"),pch=20, cex=2),
text=list(c("aaaaaaaaa","zzzzzzzzz"))) 
)

Hi:

Add a background = 'color' argument to key():

library('lattice')
xyplot(1~1,
      panel = function(x,y, ...) {
          panel.xyplot(x,y)
                  panel.abline(v=seq(0,1.4,by=0.1))
                  panel.abline(h=seq(0,1.4,by=0.1))
                }
      ,key = list (x=0.2, y=0.88,
                   points =
list(col=c("red","green"),pch=20, cex=2),
                   text=list(c("aaaaaaaaa","zzzzzzzzz")),
                   background = 'white')    )
