Spatial Location of Bramble Canes
}
\description{
The \code{brambles} data frame has 823 rows and 3 columns.


The location of living bramble canes in a 9m square plot was recorded.  
We take 9m to be the unit of distance so that the plot can be thought of
as a unit square. The bramble canes were also classified by their age.
