[R] Set size of plot: in pdf() or par() ?

[Matthieu Stigler]

Dear Ista

Thanks a  lot for your help! However, when I spedify the right size I 
wish (the same as specified in par() ) I get an error:

pdf("try.pdf", height=0.5, width=0.3)

par(pin=c(0.5, 0.3),mai=rep(0.1,4), omi=rep(0.01,4), mar=c(5,4,4,2))

plot(runif(100))

dev.off()


I don't see why my marings now would have become too small ... any idea?

Thanks!!
