Hi list,

I'm a little confused about rollapply in zoo. There is written that rollapply has replaced rapply in version 1.2-0 which is what i have. But when I tried,

> rollapply(1:100, 10, mean)

I got,

Error in rollapply(1:100, 10, mean) : no applicable method for "rollapply"

So I went back to the good old rapply

> rapply(1:100, 10, mean)

Error in rapply(1:100, 10, mean) : no applicable method for "rollapply"
In addition: Warning message:
'rapply' is deprecated.
Use 'rollapply' instead.
See help("Deprecated")

Is there a more updated version of zoo?

Thanks.
