First, thank you very much for that lattice-package, second, the code
below segfaults R:
zz <- data.frame(
y=rnorm(100),x=rnorm(100),z=round(rnorm(100)),
g=as.character(rep(1:2,50)))
xyplot(y~ x|z,data=zz,groups=g,
panel = function(x, y, subscripts, groups)
grid.text(x=x, y=y, label=groups[subscripts])
)
I'm not sure if I have understood that panel stuff right, but anyway,
it shouldn't segfault. BTW: I also unsure if I have to use the
develop-version of R & whether lattice bugs should be submitted
(because of the devel-status??).
Peter

We have an Add-Ons category on r-bugs to put it in. Lattice is closely associated with the core team, so we'd be able to track this kind of problem. With some other packages which we do not maintain, we have some trouble figuring out whether a report has been solved or whether it was even a bug in the first place (it would be nice if the original submitters would lend a hand there). As I remember it, Paul and Deepayan were somewhat vague about exactly what was required, except that you'd need something relatively recent. A segfault certainly looks like a real bug. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.

I think Paul muttered something to the effect that he knew there would be that kind of weaknesses in the code. The following runs successfully (well, at least it doesn't crash - the result looks a bit weird): library(lattice) zz <- data.frame( y=rnorm(100),x=rnorm(100),z=round(rnorm(100)), g=as.character(rep(1:2,50))) xyplot(y~ x|z,data=zz,groups=g, panel = function(x, y, subscripts, groups) grid.text(x=x, y=y, label=as.character(groups[subscripts])) ) -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
