I would like to know if there is something like r.assign('ROBJECT',
PYTHONOBJECT) in rpy2...I don't want to use R function to evaluate an object IN Python, I want to assign a matrix made in python to an R object... simone 2009/1/14 Simone Gabbriellini <simone.gabbriell...@gmail.com>: > [so sorry but I just answer your mail...
