I plan to make it into a package called Roly (for rolling). The signatures are: mov_sum(arr, window, axis=-1) and mov_nansum(arr, window, axis=-1), etc. I think of Nanny and Roly as two separate packages. A narrow focus is good for a new package. But maybe each package could be a subpackage in a super package? Would the function signatures in Nanny (exact duplicates of the corresponding functions in Numpy and Scipy) work for pandas? I plan to use Nanny in larry. I'll try to get the structure of the Nanny package in place. But if it doesn't attract any interest after that then I may fold it into larry. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
