Converting python objects for rpy2

Question

The following code is supposed to create a heatmap in rpy2

import numpy as np
from rpy2.robjects import r
data = np.random.random((10,10))
r.heatmap(data)            


        

Answer 1

For me (2.2.1) the following also worked (as documented on http://rpy.sourceforge.net/rpy2/doc-2.2/html/numpy.html):

import rpy2.robjects as ro
from rpy2.robjects.numpy2ri import numpy2ri
ro.conversion.py2ri = numpy2ri
