expo.scale is a more elaborate, and complete, version of scale. Several text options are available, but more importantly, the center and scale factors are always returned.

1	expo.scale(DATA, center = TRUE, scale = TRUE)

`DATA`	Data to center, scale, or both.
`center`	boolean, or (numeric) vector. If boolean or vector, it works just as `scale`.
`scale`	boolean, text, or (numeric) vector. If boolean or vector, it works just as `scale`. The following text options are available: 'z': z-score normalization, 'sd': standard deviation normalization, 'rms': root mean square normalization, 'ss1': sum of squares (of columns) equals 1 normalization.

A data matrix that is scaled with the following attributes (see scale):

`$'scaled:center'`	The center of the data. If no center is provided, all 0s will be returned.
`$'scaled:scale'`	The scale factor of the data. If no scale is provided, all 1s will be returned.
