I don't understand your questions above at all, but want to point out that in your example the time is completely dominated by converting the Python object "range(1000)" to R. Consider: sage: %timeit r.summary(range(1000)) 5 loops, best of 3: 2.2 s per loop sage: s = r(range(1000)) sage: %timeit r.summary(s) 125 loops, best of 3: 5.26 ms per loop -- William > > > Regards. > > -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > Visit this group at http://groups.google.com/group/sage-support?hl=en. > > -- William Stein Professor of Mathematics University of Washington http://wstein.org -- You received this message because you are subscribed to the Google Groups "sage-support" group.
