Hi thank you for the answer,
r.tell(morris, y=output['V1'])
well, my morris object in python is a dictionary.
The model output is dictionary too, but the data set I send to morris is
a list...
In R it y needs a vector, but reading the documentation of rpy...vectors
are represented as lists or dictionaries.
I tried with a tuple, array...I keep getting the list error or:
RPy_RException: Error in UseMethod("tell") :
no applicable method for 'tell' applied to an object of class
"c('double', 'numeric')"
Could it be possible that the particular method 'tell' is not supported?
Regards,
Filippo
