Yes, to further iterate on that, you can also create multiple masked views with each its own mask properties. It would be ambiguous to mix a bit-pattern NA together with standard NA's in the same mask, but you can make different specialized masked views on the same data.
Also, I like the short and concise abbreviation for 'Not Applicable', NA. It has more common uses than IGNORE. (See also here: http://www.johndcook.com/R_language_for_programmers.html#missing) Concerning the assignment, it is a bit implicit, I agree, but the representation and application of masks is also implicit. I think you only have to know that NA will be a mask assignment and not a data assignment. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
