\title{Turns a factor into a number}
\usage{
fac2num(x, force_integer = FALSE, keep_names = TRUE, ...)
}
\arguments{
\item{x}{an object.}

\item{force_integer}{logical (FALSE). Should the values returned be integers?}

\item{keep_names}{logical (TRUE). Should the values returned keep the \link{names}
of the original vector?}

\item{...}{ignored.}
}
\value{
if x is an object - it returns logical - is the object of class dendrogram.
}
\description{
Turning a factor into a number is not trivial.
Using \code{as.numeric} would only return to us the indicator numbers
and NOT the factor levels turned into a number.
fac2num simply turns a factor into a number, as we often need.
}
\examples{

x <- factor(3:5)
as.numeric(x) # 1 2 3
fac2num(x) # 3 4 5

}
