A numeric matrix containing the new data columns to be added. Must has column names to be used as new channel names. |
It is used to add extra data columns to the existing flowFrame. It handles
keywords and parameters properly to ensure the new flowFrame can be written
as a valid FCS through the function write.FCS
.
