Re: [R] pdf with an exact size
The package grid provides very convenient tools for such things: library(grid) pdf(file = square.pdf, paper = a4) pushViewport(viewport()) grid.rect(width = 100, height = 100, default.units = mm) dev.off() works just fine for me (R 2.4.1, MS WIndows XP): the printed output on my inkjet printer is exactly 100 mm x 100 mm.

[R] pdf with an exact size
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.

Re: [R] pdf with an exact size
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 __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
