Hi Guys, Need your wisdom on this.
Say I have a time series (in zoo format) like this > x <- zoo(11:21) > x 1 2 3 4 5 6 7 8 9 10 11 11 12 13 14 15 16 17 18 19 20 21 I want to do a "moving window sampling" of it. The result can either be a matrix or a dataframe like this my.super.moving.window(x, length=3, by=1) 11 12 13 12 13 14 13 14 15 14 15 16 .... 18 19 20 19 20 21 This shouldn't be new. Many many people must have done this before. Any idea what's the best(efficient and elegant) way to do this?
