\title{ Plot of the Usual Cattell's Scree Test }

\description{
  \code{uScree} Plot a usual scree test of the eigenvalues of a correlation matrix. 
 }

\usage{
 plotuScree(Eigenvalue,
             y    = NA,   
             ylab   = "Eigenvalue",
             xlab   = "Component",
             main   = "Scree Plot"
             )
 }

\arguments{
  \item{Eigenvalue}{ Vector of eigenvalues }
  \item{y}{          Not used }  
  \item{main}{       Title of the plot   (default is Scree Plot)      }
  \item{xlab}{       Label of the x axis (default is Component)  }
  \item{ylab}{       Label of the y axis (default is Eigenvalue) }
