Notice that some buggy interaction of mismatched package versions
managed to get the internal integer representation of a Date classed
variable confused with a length. I see this as of trifling interest at
best. That nice police officer over there is telling us: "Nothing to
see here folks, move on; please stop blocking the sidewalk."
Obviously this is hard for anyone to troubleshoot if you can't
reproduce it. I get the same error in R versions 12.0 and 13.0
(although I don't get the "warning zoo was built under R 13.1"
warning when I use zoo in R 12.0)

Michael,
By the way, although I replied to David's email, I was responding to
you as well. Your results were exactly what I was expecting, but I
didn't get your results.

How exactly do you mean it doesn't work? Copied from my GUI:

(Those actually line up correctly on my machine..)

Why doesn't this work?
x = zoo(1:5, as.Date('2001-01-01')+1:5)
x[as.Date('2001-01-05')]
x[as.Date('2001-01-05')] = 0
x
I think this is especially bad because it doesn't cause an error.
It lets
you do something to x, but then you can't see x again to see what it
did.
