Function for creating and embeded data set from a univariate time series given an embed size

Usage

createEmbedDS(s, emb=4)

Arguments

s	A univariate time series (can be a numeric vector or a xts object)
emb	The size of the embed for creating the data set (defaults to 4)

Details

The function creates a data set corresponding to the embed of a certain size of a given univariate time series.

For instance for an embed of size 3 each row of the data set will contain the value of the series at time t, t-1 and t-2.
