Hi All, I'd like some feedback on how mask NA should interact with views. The immediate problem is how to deal with the real and imaginary parts of complex numbers. If the original has a masked value, it should show up as masked in the real and imaginary parts. But what should happen on assignment to one of the masked views? This should probably clear the NA in the real/imag part, but not in the complex original. However, that does allow touching things under the mask, so to speak.
Things get more complicated if the complex original is viewed as reals. In this case the mask needs to be "doubled" up, and there is again the possibility of touching things beneath the mask in the original. Viewing the original as bytes leads to even greater duplication. My thought is that touching the underlying data needs to be allowed in these cases, but the original mask can only be cleared by assignment to the original. Thoughts? Chuck
