scaleTransform: Create the definition of a scale transformation function to...

In flowCore: flowCore: Basic structures for flow cytometry data

Description

Create the definition of the scale Transformation that will be applied on some parameter via the transform method. The definition of this function is currently x = (x-a)/(b-a). The transformation would normally be used to convert to a 0-1 scale. In this case, b would be the maximum possible value and a would be the minimum possible value.

Usage

scaleTransform(transformationId="defaultScaleTransform", a, b)

Arguments

transformationId	character string to identify the transformation
a	double that corresponds to the value that will be transformed to 0
b	double that corresponds to the value that will be transformed to 1

Value

Returns an object of class transform.
