[R] import data from splus

I have a somewhat similar problem.  I also need to move huge, somewhat
complicated objects from Splus5 to R.  I need data.restore() in R 
(in my case it should be S4/Splus5 aware).

I took a quick look at the Rstream manual, but I didn't see anything that
I could easily use/modify for this problem (right?).

Is there something out there I could use, or will data.dump()/data.restore()
need to be written for R? (BTW I think this is not an R issue per se, but
rather an R-S interface issue -- it is a fact that most of my collaborators
use Splus.)

If that really will cost forever, then I think any route will take a long
time (and perhaps let that be a lesson not to store data in a proprietary

You may find that the function readSdata in package Rstreams helps.
The normal route is to dump in S-PLUS and source in R.
