DSD_ScaleStream: Scale a Stream from a DSD

Description

Make an unscaled data stream into a scaled data stream.

Usage

DSD_ScaleStream(dsd, center=TRUE, scale=TRUE, n=1000, reset=FALSE)

Arguments

dsd

A object of class DSD that will be scaled.

center, scale

logical or a numeric vector of length equal to the number of columns used for centering/scaling (see function scale).

n

The number of points used to creating the centering/scaling

reset

Try to reset the stream to its beginning after taking n points for scaling.

An object of class DSD_ScaleStream (subclass of DSD_R, DSD).

Details

# scale stream using 100 points
stream_scaled <- DSD_ScaleStream(stream, n=100)
