In RGLab/flowCore: flowCore: Basic structures for flow cytometry data

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

Description

Create the definition of the quadratic Transformation that will be applied on some parameter via the transform method. The definition of this function is currently x <- a*x\^2 + b*x + c

Usage

quadraticTransform(transformationId="defaultQuadraticTransform", a = 1, b = 1, c = 0)

Arguments

transformationId	character string to identify the transformation
a	double that corresponds to the quadratic coefficient in the equation
b	double that corresponds to the linear coefficient in the equation
c	double that corresponds to the intercept in the equation

Value

Returns an object of class transform.
