Tim,
Add the argument as.table=TRUE to your call:
bwplot(y~x|id, horizontal=FALSE, as.table=TRUE)

Dear List,
I know this has been covered before, but I don't seem to be able to get it right. I am constructing a boxplot in lattice and can't get the scales in the correct alphebetical order. I have already read that this is due to the way factors are treated, and I have to redefine the levels of the factors. However, I have failed.
As a simple example:
library(lattice)
id<-rep(letters[1:9], each=20)
x<-rep(seq(1:10),each=18)
y<-rnorm(180,50,20)
#Reverse alphebetical order
bwplot(y~x|id, horizontal=FALSE)
#alphebetical order reading right to left
id<-factor(id,levels = sort(id,decreasing = TRUE))
bwplot(y~x|id, horizontal=FALSE)
It appears that bwplot plots scales from the bottom left to the top right. If
so my factor levels would need to be levels=c(7,8,9,4,5,6,1,2,3). I tried that
but can't seem to get the factor function to work.
#Did not work!
id<-factor(id,levels=c(7,8,9,4,5,6,1,2,3),lables=letters[1:9])
Your help would be greatly appreciated.
