\usage{
od_coords2line(odc, crs = 4326, remove_duplicates = TRUE)
}
\arguments{
\item{odc}{A data frame or matrix representing the coordinates
of origin-destination data. The first two columns represent the
coordinates of the origin (typically longitude and latitude) points;
the third and fourth columns represent the coordinates of the destination
(in the same CRS). Each row represents travel from origin to destination.}

\item{crs}{A number representing the coordinate reference system
of the result, 4326 by default.}

\item{remove_duplicates}{Should rows with duplicated rows be removed? \code{TRUE} by default.}
}
