Hi Dirk,
ok - now it works. All the MACROs scared me a little,
but now I've found them in Rinternals.h and Rdefines.h .
There was a section in the official manual referring to these,
but this section was not introduced for embedded R but for calling c++
from R - this is why i didn't find it at first.
Thanks again for you help!!
Best
Peter

I think you are halfway there. You have an embedded R session, you can assign
variables and evaluate commands. You also see RCpp and how to pass data
out. I think all I did at that point was to invert a few of those functions
to pass data in ... and there you have it in your embedded R session.
Hope this helps, Dirk
