Dear R list,
The code below puts qq-plots for two of three groups on the one
plot. However the legend includes all three groups, ie the auto.key
ignores the subset instruction. Is there an easy way to get around
this, so that only those groups plotted are included in the legend?
y1<-rnorm(100); y2<-rnorm(100)+1; y3<-rnorm(100)+2; y<-c(y1,y2,y3)
fact=factor(c(rep(1,100),rep(2,100),rep(3,100)))
require(lattice)
qqmath(~y,groups=fact,auto.key=list(corner=c(0,1)),subset=fact!=2)
Many thanks,
John Field
