\title{Convert origin-destination data from wide to long format}
\usage{
odmatrix_to_od(odmatrix)
}
\arguments{
\item{odmatrix}{A matrix with row and columns representing origin and destination zone codes
and cells representing the flow between these zones.}
}
\description{
This function takes a matrix representing travel between origins
(with origin codes in the \code{rownames} of the matrix)
and destinations
(with destination codes in the \code{colnames} of the matrix)
and returns a data frame representing origin-destination pairs.
}
\details{
The function returns a data frame with rows ordered by origin and then destination
zone code values and with names \code{orig}, \code{dest} and \code{flow}.
}
\examples{
odmatrix <- od_to_odmatrix(flow)
odmatrix_to_od(odmatrix)
flow[1:9, 1:3]
odmatrix_to_od(od_to_odmatrix(flow[1:9, 1:3]))
