How to remove first blank page when lapply is used?

Question

I have a simple question. When we would like to remove the first blank page for an individual plot, we set

pdf("abc.pdf", onefile=FALSE)

However, when we are plotting using lapply, setting onefile=FALSE will only print the last plot.

I wonder how we solve this? Thanks!

When I tried this code on a Linux box running R 4.0.4 it produced five one page pdf files:

for(i in 1:5){ pdf(file=paste0("x",i, '.pdf')); plot(1,1); dev.off()}

If this doesn't succeed on your setup, then you need to describe it better.

I then tried for completeness:

lapply(1:5, function(y){pdf(file=paste0("xx",y, '.pdf')); plot(1,1); dev.off() })
# same results
