Embeds the time series x into a low-dimensional Euclidean space.

### Usage

embed (x, dimension = 1)


### Arguments

 x a numeric vector, matrix, or time series. dimension a scalar representing the embedding dimension.

### Details

Each row of the resulting matrix consists of sequences x[t], x[t-1], ..., x[t-dimension+1], where t is the original index of x. If x is a matrix, i.e., x contains more than one variable, then x[t] consists of the tth observation on each variable.
