squareroot-class {flowCore} | R Documentation |
Square root transform class defines a transformation defined by the function
f(parameter,a)= sqrt{ |{frac{parameter}{a}|}}
Objects can be created by calls to the constructor
squareroot(parameters,a,transformationId)

Class "singleParameterTransform"
, directly.
Class "transform"
, by class "singleParameterTransform", distance 2.
Class "transformation"
, by class "singleParameterTransform", distance 3.
Class "characterOrTransformation"
, by class "singleParameterTransform", distance 4.
No methods defined with class "squareroot" in the signature.
The squareroot transformation object can be evaluated using the eval method by passing the data frame as an argument.The transformed parameters are returned as a column vector. (See example below)
