I agree. If you have Numeric installed (which I do) then r.diag() should return a Numeric array, not a list of lists. This looks like the same problem discussed in this thread: http://sourceforge.net/mailarchive/message.php?msg_id=15307721 which does not seem to have been resolved. I don't want to get involved in the Rpy mailing list but I would suggest posting a very simple question asking why the result of r.diag() is not a Numeric array. Perhaps this will lead to a solution. > The code snippet i was talking about is on page 15 and 16 of the rpy > reference guide http://rpy.sourceforge.net/rpy/doc/rpy.pdf ; the > examples just don't work and i am lacking enough python experience to > see why :-S. > > What i'm trying to do now is : > > ---- > from rpy import * > > class Test: > def as_r(self): > return [[1,2,3,4,5],[2,3,4,5,1],[3,4,5,1,2],[4,5,1,2,3],[5,1,2,3,4]] > > if __name__ == "__main__": > a=with_mode(NO_CONVERSION, Test)() > r.kmeans(a, 2, 5, 10, "Forgy") I don't see how this will help. My understanding is that as_r() should return an Robj, not a Python object. I think this code is the same as passing a list of lists directly to kmeans.
