Reorganizes a single observed time series into an embedded matrix. The embedded matrix is constructed with replicates of an individual time series that are offset from each other in time. The function requires two parameters, one that specifies the number of observations to be used (i.e., the number of embedded dimensions) and the other that specifies the number of observations to offset successive embeddings

## Arguments

- x
Numeric vector. An observed time series to be reorganized into a time-delayed embedded matrix.

- E
Numeric (length = 1). Number of embedded dimensions or the number of observations to be used.

`E = 5`

, for example, will generate a matrix with five columns corresponding to five consecutive observations across each row of the embedded matrix- tau
Numeric (length = 1). Number of observations to offset successive embeddings. A tau of one uses adjacent observations. Default is

`tau = 1`
