I have isolated an error that can be reproduced by the following code.
The same thing happens in 2.8.0pat and 2.9.0dev. It looks like the
try() code is ending up in the display list, or something?
library(grid)
library(lattice)
xyplot(1:100 ~ 1:100)
test <- try(downViewport("pageAnnotationVp"), silent = TRUE)
downViewport(trellis.vpname("toplevel"))
pushViewport(viewport(name = "pageAnnotationVp", yscale = c(1, 0)))
upViewport(0)
## resize device to trigger a couple of redraws...
Error: protect(): protection stack overflow
Enter a frame number, or 0 to exit
1: no.children(<environment>)
2: ls(children, all.names = TRUE)
3: try(name)
4: tryCatch(expr, error = function(e) {
5: tryCatchList(expr, classes, parentenv, handlers)
6: tryCatchOne(expr, names, parentenv, handlers[[1]])
7: doTryCatch(return(expr), name, parentenv, handler)
