Hi, I have a tmp object which is stream of numbers of -1, 0, 1, 2. I want
to make values from 2007-09-05 to 2007-09-13 to be 0, and from 2007-09-14 to
2007-09-27 to be 1, and 2007-09-28 to 2007-10-03 to be 0 again. To logic is
that suppose t(i)=1, then t(i+n)=1 if t(i+n) already is {0 or 1}, but not
2. However, if i(i) is already {0 or 2}, then t(i+n) = 0, where n represent
the next n days. What is the best approach without loops? Thank you.
