R: Extract the transformation parameters from a flowTransResult
extractParams
R 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.
