pcqm.method: Mangrove Point-Centered Quarter Method Analysis

In gshideler/mangroveStructure: tools for calculating mangrove forest structure

Description

This function allows you to estimate mangrove forest structure based on sampling using the Point-Centered Quarter Method (PCQM). See Cottam and Curtis (1956) for informaiton on PCQM.

Usage

pcqm.method(x, samplingpoint = "samplingpoint", dist = "dist",
  species = "species", dbh = "dbh", height = "height")

Arguments

samplingpoint	Column name in data frame for sampling points (numerical). Default name is "samplingpoint". First sampling point must be 1.
dist	Column name in data frame for distance from tree to sampling point. Default name is "dist". Values must be in meters.
species	Column name in data frame for species. Default name is "species".
dbh	Column name in data frame for diameter at breast height. Default name is "dbh". Values must be in centimeters.
height	Column name in data frame for height (Optional). Default name is "height". Values must be in meters. When included, additional height-related outputs are displayed.

Examples

pcqm.method(mangrove_data)
pcqm.method(mangrove_data, dbh = "Diameter", height = "Tree_Height", samplingpoint = "Sampling_Point")
