plotscale: Rescaling the individuals occurred in a Forestry Dynamic Plot

Description

Rescaling the individuals occurred in a Forestry Dynamic Plot. It will add a column called "gridnames". This function could make the analysis based on different scales easier.

Usage

plotscale(inputdata, len = NULL, wid = NULL, scale = NULL)

Arguments

inputdata

A data matrix inputdata that has "tag", "x" and "y".

len

Length of the FDP

wid

Width of the FDP

scale

Size of the quadrat

Value

A column will be added to the input matrix , to represent the position for each individual. For example, "X5Y20" means the corresponding individual lies at cell X = 5,y = 20. The labels could be further used to represent the species matrix.

Details

The input data must he following columns, "Tag" : the tag number for each individual in the FDP. "x", "y" are the coordinats of the individuals in the FDP.
