\title{
Computes the inverse of the transform defined by the 'logicleTransform' function}

\description{
  inverseLogicleTransform can be use to compute the inverse of the 
  Logicle transformation. The parameters w, t, m, a for calculating 
  the inverse are obtained from the 'trans' input passed to the 
  'inverseLogicleTransform' function. (The inverseLogicleTransform 
  method  makes use of the C++ implementation of the inverse logicle transform 
  contributed by Wayne Moore et al.) 

}
\usage{
inverseLogicleTransform(transformationId, trans)
}


\arguments{
  \item{transformationId}{ A name to assigned to the inverse transformation. Used
  by the transform routines. } 
  \item{trans}{An object of class 'transform' created using the 'logicleTransform'
   function. The parameters w, t, m, a for calculating the inverse are obtained from the 'trans' input passed to the 
  'inverseLogicleTransform' function. }
