I totally agree.  I'm just feeling my way along.  I have to be sure I
have a workable plan to manage the output before I get too much further
along.  In the past, I have used Axum to make graphs and I liked it
pretty well, but now I'm trying to wean myself of the pointing and
clicking and MS Windows. 

Maybe you should tell me the best way to attack  my problem. I never
want to print to a printer, I always want to save the graphs to files
which can then be imported into word processors or some kind of editor.
I'm debating whether to try writing with Lyx in order to generate Tex
output.  In the past, I've used editors like MS word or Applixware
Words.  I'm starting a project in which I will probably generate 50 or
100 figures from start to end, and when the manuscript is finished, I
don't want to have to rerun all the figures to resize them by one inch
or something.  My experience is that, if I output a gif that does not
fit on the page, then I've shot myself in the foot because resizing the
graph makes all the text in it too small.  I don't think postscript is
immune to this problem, but you can for sure convince me I'm wrong.  I
was considering the tex output from R, but I don't know what to do with
it after I get it :)  I've not learned how to incorporate them into Lyx,
but I think that may be a Lyx configuration problem, I'm looking into it

So, as you can see, I'm not a complete novice, but I don't have a
definite plan for how to do this manuscript, and I'm open to your

Could you please explain? I have read ?dev.copy over and over again, and
I don't see what you mean.  I want it copied to a file, not a device. 
dev.copy has no file= option.
