\title{Compute Areas of Tiles in a Tessellation}
\description{
Computes the area of each tile in a tessellation.
}
\usage{
tile.areas(x)
}
\arguments{
\item{x}{A tessellation (object of class \code{"tess"}).}
}
\details{
A tessellation is a collection of disjoint spatial regions
(called \emph{tiles}) that fit together to form a larger spatial
region. See \code{\link{tess}}.
This command computes the area of each of the tiles
that make up the tessellation \code{x}.
The result is a numeric vector
in the same order as the tiles would be listed by \code{tiles(x)}.
}
\value{
A numeric vector.
