Spatial Location of Bramble Canes

Description

The 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.

Usage

brambles

Format

This data frame contains the following columns:

x

The x coordinate of the position of the cane in the plot.

y

The y coordinate of the position of the cane in the plot.

age

The age classification of the canes; 0 indicates a newly emerged cane, 1 indicates a one year old cane and 2 indicates a two year old cane.
