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.

You need to open the pdf/poscript first and then plot...see ?postscript
# open the file "foo.ps" for graphics output
postscript("foo.ps")
# produce the desired graph(s)
dev.off() # turn off the postscript device

All your plotting will now go into device "B" until you close it by dev.off(), then all further plotting goes into device "A" - unless you start another device.
