Is it possible to create a pdf output file with an (as nearly as
possible) exact size?
For example, if I want to draw in an A4 paper (210 x 297 mm) a
square of 100 x 100 mm, how can I do it?
FWIW, about 6 months ago I learned here how to create an exact
png image. For example, if I want a 500 x 500 black square in
a 1000 x 1000 white png, occupying the center of the png, the
procedure is this:
png("image.png", width=1000, height=1000, bg="white")
par(mar=c(0,0,0,0)) # reset margins
plot(0, xlim=c(0, 999), ylim=c(0, 999), col="white")
par(usr=c(0, 999, 0, 999))
points(c(250, 250, 749, 749, 250), c(250, 749, 749, 250, 250),
type="l", col="black")
dev.off()
However, I don't know how do this with a pdf monstr... oops... file.

I must be stupid and/or crazy... I figured out the solution a few minutes after I asked :-/> Is it possible to create a pdf output file with an (as nearly as > possible) exact size?Yes: pdf("a4.pdf", width=210, height=297, bg="white", paper="a4") par(mar=c(0,0,0,0)) # reset margins plot(0, xlim=c(0, 210), ylim=c(0, 297), col="white") par(usr=c(0, 210, 0, 297)) points(c(100, 100, 200, 200, 100), c(100, 200, 200, 100, 100, 100), type="l", col="black") dev.off() Alberto Monteiro
