1. rollapply is for creating zoo objects from zoo objects --
not for creating lists from zoo objects. 2. The
subscripting is wrong. 3. Its possible that you need a different
representation for out but that depends on what you want to
do with it. At any rate try this and note that there is no
zoo
Dear R users.
I have zoo object "size_june" containing market-capital values:
> dim(size_june) # market-cap data of 625 firms for 20 years
[1] 20 625
> class(size_june)
[1] "zoo"
> size_june # colnames = "size.firmcode"
size.34020 size.4710 size.11050 size.10660 size.9540 size.8060
