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.

How exactly do you mean it doesn't work? Copied from my GUI:> x = zoo(1:5, as.Date('2001-01-01')+1:5) > x[as.Date('2001-01-05')]2001-01-05 4> x[as.Date('2001-01-05')] = 0 > x2001-01-02 2001-01-03 2001-01-04 2001-01-05 2001-01-06 1 2 3 0 5 (Those actually line up correctly on my machine..)

What was the "this" that you think was bad? I hope you are not asking that R ask users to confirm every assignment with a popup window. -- David Winsemius, MD West Hartford, CT
