empty pages in xyplot (2.4.0)
In 2.4.0 (and SVN) I am seeing xyplot creating empty pages for high page
counts in layout - contrary to the manual which says high page counts should
not matter. Everything works fine in 2.3.1.
library("lattice")
A<-data.frame(x=1:10, y=sin(1:10), z=round(1:10/3))

data frame subset patch, take 2
Hi Robert,
Here is the second iteration of data frame subset patch.

Changes:

* Changed x[[j]]<- assignment to x<-.subassign2(x, j, ..) to fix the problem
with the previous patch.
