\title{ Methods to append flowFP fingerprints to a flowFPPlex }


\description{
  
  This method joins one or more \code{\link{flowFP}} objects into a
  \code{\link{flowFPPlex}}. Conceptually, each instance's fingerprint feature
  vector is extended. An error will occur if the sample names and the class 
  names differ. If we imagine the fingerprints as a matrix where columns are
  features and the rows are instances, this method binds the columns
  onto the existing fingerprint matrix.

  \code{\link{flowFPPlex}} methods:

  \describe{
  
  \item{x = "flowFPPlex", values = "flowFP", after = length(x@fingerprints)}{
        Appends a fingerprint onto a flowFPPlex. }

  \item{x = "flowFPPlex", values = "list", after = length(x@fingerprints)}{
        Appends a list of fingerprints to a flowFPPlex. }
          
  \item{x = "flowFPPlex", values = "flowFPPlex", after = length(x@fingerprints)}{
        Combines two flowFPPlex-es into one. }	
  }
}

\details{

  These methods append one or more fingerprints into a flowFPPlex.
