ratio-class {flowCore} | R Documentation |
ratio transform calculates the ratio of two parameters defined by the function
f(parameter_1,parameter_2)=frac{parameter_1}{parameter_2}
Objects can be created by calls to the constructor
ratio(parameter1,parameter2,transformationId)
.

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