[R] handle graph size in eps

Sorry for the lack of information.
I'm indeed under Windows. I indeed used the menu "save as" in the graph
window.
The matter with the eps obtained was the width of the graph which is lower
than what I had on the screen or what I got when I saved it as a JPEG file.
I tried the "postscript" command
postscript("test.eps",width=14,height=6)
print.it=TRUE
{
#windows(width=6,height=6)
par (
fin=c(6,6)
,mai=c(1,1,0.5,0.5)
,mfrow=c(1,2)
,cex.axis=1.5
,cex.lab=1.5)
dens<-density(DATA1.y[2,]-mean(DATA1.y[2,]),kernel="gaussian")
xlimit<-range(dens$x)
ylimit<-range(dens$y)
hist(
DATA1.y[2,]-mean(DATA1.y[2,])
,xlim=1.1*xlimit
,xlab=expression(q[e])
,ylim=1.1*ylimit
,probability=T
,main="Random distribution around y")
lines(dens,col=2,lwd=2)
qqnorm(DATA1.x[1,])
}
dev.off()
rm(dens,xlimit,ylimit)
I barely managed to get the ratio I want for the graph

But still when I change the width in the poscript command from 12" to 20"
for instance, it doesn't change anything... why?
BTW how do I stop the pipe between a poscript file and R without closing R?

The preferred name is windows().

How exactly? I know at least three ways to do that. I am guessing that as
you didn't tell us you were on Windows, you also didn't tell us that you
used the menu on the windows() device, but these details do matter.

Not telling us what you don't like about this plot.
I think you should consider using dev.copy2eps(), which will give you more
control. Or even better, calling postscript() directly.
