My understanding is that people using missing data for object arrays will use the "None" object. I don't think it's appropriate to ever have NULL pointers for OBJECT arrays except during initialization. For example, empty([10,5], dtype=object) produces an array of "None". What are you planning to do with None's? You could treat them as nans, I would think. -Travis > > Chuck > _______________________________________________ > NumPy-Discussion mailing list > [email protected] > http://mail.scipy.org/mailman/listinfo/numpy-discussion _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
