scaleTransform {flowCore}R Documentation

Create the definition of a scale transformation function to be applied on a data set

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, a, b)

Arguments

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

Value

Returns an object of class transform.
