Arguments

x

Object of class "indscal" (output from indscal), class "parafac" (output from parafac), class "parafac2" (output from parafac2), class "sca" (output from sca), or class "tucker" (output from tucker).

mode

Character indicating which mode to rescale.

newscale

Desired root mean-square for each column of rescaled mode. Can input a scalar or a vector with length equal to the number of factors for the given mode.

absorb

Character indicating which mode should absorb the inverse of the rescalings applied to mode (cannot be equal to mode).

...

Ignored.

Details

See indscal, parafac, parafac2, sca, and tucker for more details.

Value

Same as input.
