R help - Jun 2011 - R graphs differ from exported one

Hello everybody! This is my first mail so I'll write a couple of lines
of self-introduction.
My name is Massimiliano, I'm from Italy and I'm studying Mathematical
Engineering.
I started using R in my Statistics course and have to use it to make a
project which I'll discuss at the end of the course.

The problem I'd like to ask you about follows.
Suppose I have imported a datafile with the classic command

dat <- read.table('file', header=T)

and wanted to see if my data are Normal-like or not.
I can accomplish this with the command

qqnorm (col)

where 'col' is the column in the datafile 'file'.
Now, the graph that appears is very nice: indeed it has a title, two
axes with their labels and all the rest;
but when I give commands

postscript(file="plot.eps", onefile=FALSE)
qqnorm (col)

to save the graph to a file "plot.eps" to include it in a TeX, the
file
created has nothing to do with the former one: it only has "the graph
part", i.e. no title, no labels, no axes....

I searched in the documentation but found nothing; the same on the
forum.
What should I do?
I'm running R 2.12.1 on Ubuntu Linux 10.04 LL 64-bit

Thanks for help to everybody :)

Hmm, did you shut the device down afterward (i.e., call dev.off() )?
I do not have any logic why that would induce the behavior you say you
are getting, but this works just fine for me:

postscript("tmp.eps", onefile = TRUE)
qqnorm(rnorm(20))
dev.off()

and creates the attached file (possibly not attached for the list, but
you should get it).

I use R under Windows, and I've seen the same sort of thing. I usually save
graphs as PDF or PNG files, which works fine, but on the rare occasions I've
tried to save graphs as Postscript, some of the graphs end up saving with
bits missing.
