thanks for taking the time!

Ok...

Could you or somebody else enhance my OP in this sence to
demonstrate the effect intended? I've fiddled around with
`postscrict' and `ps.options' all day long but haven't reached a
working file. The problem is most likely sitting in front of the
keyboard.

Not knowing if it's actually going to help me: Can you point me
to the file which does the conversion to the *.tex file? I've
tried `locate sweave' on my linux box and there wasn't anything
in the results concerning the conversion to TeX. 

I'm one of those guys that wants to have nice looking results at
the end with all plots having the same layout. I'm biased by the
following tools at the moment:

1. PSTricks (within LaTeX; low level; good for publications)

2. export from Matlab7.0.1 -> (e)ps for LaTeX (via PSFrag
replacement of fonts / publishable) [1] 

3a. normal export from R -> (e)ps for LaTeX via library Hmisc
(PSFrag: font replacement untested / publishable?)

3b. export from R "sweaved" into LaTeX -> Sweave and problem
above. I use this option at least once a month to feedback-myself
of current results and very much enjoy the feature of not having
to fiddle-fart around with layouts. And having the `\Sexpr'
available.... indespensable. I can look at my results months
later and know what I've done.


1==3a : fine for high-end publishing.

2 and 3b : is a good routine.

Combining 3b with 1 would be nice.


Ideas?

Patrick
