\title{Numeric Encoding of a Partitioning}
\description{
Converts a vector interpreted as a classification or partitioning
into a numeric vector.
}
\usage{
partconv(x, consec=TRUE)
}
\arguments{
\item{x}{
A vector interpreted as a classification or partitioning.
}
\item{consec}{
Logical value indicating whether or not to consecutive class
numbers should be used .
}
}
\value{
Numeric encoding of \code{x}.
When \code{consec = TRUE}, the distinct values in \code{x} are numbered by
the order in which they appear.
When \code{consec = FALSE}, each distinct value in \code{x} is numbered by
the index corresponding to its first appearance in \code{x}.

\examples{
partconv(iris[,5])
set.seed(0)
cl <- sample(LETTERS[1:9], 25, replace=TRUE)
partconv(cl, consec=FALSE)
partconv(cl, consec=TRUE)
