(PR#9035) apparent problem in how PDF evaluates its arguments
It was already in the process of being changed, hence the first seven
lines of the function. That lapply is no longer needed and has been
removed (but was not yet committed).
We do normally ask that problems with R-devel ('Under development
(unstable)') not be sent to R-bugs: as is quite often the case this is
something that is under active development.

Yup. Should be 3, as far as I can see. Or maybe better pframe <- parent.frame() new <- lapply(Call, function(x) eval(x, pframe))
The error does not happen, for example, when "pdf" is replaced by "png".
options(error=recover)
## debug(pdf)
makepdf1 = function(p=1) {
pdf("test.pdf", pointsize=p)
plot(1:7)
dev.off()
}
z=1
makepdf2 = function() {
pdf("test.pdf", pointsize=z)
plot(1:7)
dev.off()

makepdf2()
