I am need of assistance programming the following scenario:
I have two vectors composed of 0's and 1's. Vector "A" has 5% 1's
(and 95% 0's) while Vector "B" has 50% 1's and 50% 0's.
First, I would like to change Vector B to have a "1" in every place
that Vector A also has a "1" (in other words, I will then have more
than 50% 1's in Vector B once this step is completed).
Then, I would like to *randomly* return Vector B back to a 50/50
distribution of 1's and 0's.
I greatly appreciate any proposed programming methods.
