One Question: if I make a lattice-plot (beware: under development!) with a special layout e.g. c(2,2,4): p1 <- xyplot(y~x|id,data=data,layout=c(2,2,3)) is there a way to print.trellis e.g. the second page of the trellis object "p1"? print.trellis(p1,page=2) #!wrong! I want this to automatically dev.print the pages (no, I don't want multiple postscript pages). If this isn't possible I'll do the old trick with a for-loop...

Trellis plots should have defaults which depend on the device (I don't think lattice does yet) and so should not be copied between devices as dev.print does. Rather, just print to the device you want to use, or print multiply to multiple devices. As just one example, trellis uses cyan on grey on a screen, and blue (I think) on white on a paper device.> postscript pages).

This layering means that user code that is written for trellis, and which involves anything more than straightworward function calls, is unlikely to carry directly across to lattice. There are however large benefits in the grid/lattice separation of the code into layers. The grid library can be a basis for new graphics functions, or libraries, that greatly extend lattice, or do quite different things from lattice. The code in trellis is not layered in this way. A consequence is that it would be difficult and (perhaps even more importantly) generate some pretty contorted code, if one were to write another graphics library on top of trellis. Paul Murrell will probably think this so obvious that it is hardly worth saying, but maybe it needs to be said.

[R] SOLVED: multiple lattice-pages (development package!)...
Not seen at first reading, there is one arg in trellis.args:
page: a function of one argument (page number) to be called after
drawing each page.
so something like:
xx <- data.frame(x=rnorm(100),y=rnorm(100),g=as.factor(round(rnorm(100))))
tmp <- 1
xyplot(y~x|g,data=xx,layout=c(1,1),page function(...){
dev.print(postscript
,file=paste("/tmp/test",tmp,".ps",sep=""))
tmp <<- tmp + 1
}
)
One big thank to the people, who provide "lattice" + "grid"!
Peter
