Spatial Location of Bramble Canes
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.
This data frame contains the following columns:
The x coordinate of the position of the cane in the plot.
The y coordinate of the position of the cane in the plot.
The age classification of the canes;
0indicates a newly emerged cane,
1indicates a one year old cane and
2indicates a two year old cane.
