Hi thanks for the advices,
I tried with rpy2 and i got some results executing the r-code through:
robjects.r([code])
but the data structure are not clear and is not straightforward
understand if the result would be the same in R.
I'll keep trying...
Anyway I think that the integration between python and R is possible
only if you need a bit of one into the other...an I wrong?
Is there some one who has developed large projects integrating both?
Regards,
Filippo
