If you are referring to rollmean in the zoo package then na.pad = TRUE
will cause the output to be the same length as the input:
> library(zoo)
> rollmean(zoo(1:10), 3, na.pad = TRUE)
1 2 3 4 5 6 7 8 9 10
NA 2 3 4 5 6 7 8 9 NA
> rollmean(zoo(matrix(1:10, 5)), 3, na.pad = TRUE)
1 NA NA
2 2 7
3 3 8
4 4 9
5 NA NA
