Moving windows solution
Try this:
BOD # comes with R
Time demand 1 1 8.3 2 2 10.3 3 3 19.0 4 4 16.0 5 5 15.6 6 7 19.8
rollapply(as.zoo(as.matrix(BOD)), 3, sum)
2 6 37.6 3 9 45.3 4 12 50.6 5 16 51.4 rollapply has many more options and capabilities. See ?rollapply

Thanks Gabor, But the function I intend to apply requires data.frame object ... not zoo() object have you had expirience with this kind of problems. On Sep 27, 3:59 pm, "Gabor Grothendieck" <ggrothendi... at gmail.com> wrote:
rollapply in the zoo package does that. See ?rollapply and the three accompanying vignettes.
library(zoo) z <- zoo(1:10) rollapply(z, 3, sum)

Is there an implementation of moving window functionality so I can apply any function while sliding trough window.
Thanks
