Hello useRs,
I'd like to perform a moving average on the dataset, xx. I've tried
combining the functions Reduce and rollmean but it didn't work.
> r <- function(n) rollmean(n, 2) # where 2 = averaging interval
> output < - Reduce("r", x)
Error in f(init, x[[i]]) : unused argument(s) (x[[i]])
Is there anything wrong with the code in the first place?
where
> x
[[1]]
V1 V2 V3
[1,] 1 1 1
[2,] 2 2 2
[3,] 3 3 3
[[2]]
V1 V2 V3
[1,] 4 4 4
[2,] 5 5 5
[3,] 6 6 6
[[3]]
V1 V2 V3
[1,] 7 7 7
[2,] 8 8 8
[3,] 9 9 9
The moving average is to be performed on
1,4,7 = (1+4)/2 , (4+7)/2
2,5,8 = ..
3,6,9 = ..
Thanks
Muhammad
