After changing v assignment to:
v = robjects.IntVector(range(1000))
... everything worked correctly and quickly (for my machine anyway).
sage: %timeit summary(v)
125 loops, best of 3: 1.59 ms per loop
sage: print(summary(v))
Min. 1st Qu. Median Mean 3rd Qu. Max.
0.0 249.8 499.5 499.5 749.2 999.0
Thanks!
