SpWd_Area_calc: Sapwood area calculation

In TDPanalysis: Granier's Sap Flow Sensors (TDP) Analysis

Description

Calculate sapwood area based on diameter, heartwood diameter and sapwood fraction

Usage

SpWd_Area_calc(diam, SpWd_frac = 1, HtWd_diam = 0)

Arguments

diam	Vector with diameter.
SpWd_frac	Numerical (from 0 to 1). Indicate the fraction of the diameter which is sapwood
HtWd_diam	Vector with diameter of the heartwood.

Details

If SpWD_frac and HtWd_diam are both entered, the function will return an error. Units of "diam" and "HtWd_diam" should be the same.

Value

Return a numerical vector containing the sapwood area

Examples

diam = c(12,14,16,13,15)
SpWd_Area_calc(diam=diam, SpWd_frac=0.2)

Example output

[1] 108.5734 147.7805 193.0195 127.4230 169.6460
