transform: tranform the flow data asssociated with the GatingSet

Description Usage Arguments Value Examples

Description

The transformation functions are saved in the GatingSet and can be retrieved by gh_get_transformations. Currently only flowJo-type biexponential transformation(either returned by gh_get_transformations or constructed by flowJoTrans) is supported.
