\title{
Get the nearest point on a line to a given point
}
\description{
This function calculates the coordinates of the nearest point on a line to a
given point. This function does not work with geographic coordinates.
}
\usage{
nearestPointOnLine(coordsLine, coordsPoint)
}
\arguments{
\item{coordsLine}{
Matrix with coordinates of line vertices. Each row represents a vertex.
}
\item{coordsPoint}{
A vector representing the X and Y coordinates of the point.
}
}
