exponential-class {flowCore} | R Documentation |
Exponential transform class defines a transformation given by the function
f(parameter,a,b)=e^{parameter/b}*\frac{1}{a}
Objects can be created by calls to the constructorexponential(parameters,a,b)
.

Class "singleParameterTransform"
, directly.
Class "transform"
, by class "singleParameterTransform", distance 2.
Class "transformation"

No methods defined with class "exponential" in the signature.
The exponential transformation object can be evaluated using the eval method by passing the data frame as an argument.The transformed parameters are returned as a matrix with a single column
