| xegaDfScaleFactorFactory {xegaDfGene} | R Documentation |
Configure the scale factor function for differential mutation.
Description
xegaDfScaleFactorFactory implements the selection
of one of the scale factor functions in this
package by specifying a text string.
The selection fails ungracefully (produces
a runtime error) if the label does not match.
The functions are specified locally.
Current support:
"Const" returns
ConstScaleFactor."Uniform" returns
UniformRandomScaleFactor.
Usage
xegaDfScaleFactorFactory(method = "Const")
Arguments
method |
A string specifying the scale factor function. |
Details
In the literature, several approaches have been suggested. For a review see Sharma et al. (2019).
Value
A scale factor function for genes.
