R: Extract the transformation parameters from a flowTransResult
extractParamsR Documentation

Extract the transformation parameters from a flowTransResult

Description

Extracts the transformation parameters from a flowTransResult object

Usage

extractParams(x, dims = NULL)

Arguments

x

An object of type flowTransResult returned by a call to flowTrans

dims

A character vector specifying the dimensions for which to extract transformation parameters.

Value

A list of length length(dims). Each element contains a vector of parameters for transforming the particular dimension.The names of the list elements correspond to the names of the dimensions.

Note

flowTrans estimates common transformation parameters.
