Hello,



I would like to learn how to create a pdf and a postscript file from an R
graphic.

For example, I tried :



plot(1)              # example

pdf("H:/Perso/essai.pdf")

postscript("H:/Perso/essai.ps")



But the pdf document created is empty.



How do these functions work ?



Thank you very much.
