get_site: Calculates missing stand-level variable from the set: AD, HD,...

In sgezan/Nothopack: G&Y Forest Simulator for Roble-Rauli-Coigue Stands in Chile

Description

When two of stand level variables: dominat age (AD), dominant height (HD) and site index (SI) are given, it returns the value of the remaining stand-level parameter.

Usage

get_site(DOM.SP, ZONE, AD = NA, HD = NA, SI = NA)

Arguments

DOM.SP	Dominant species (1: Rauli, 2: Roble, 3: Coigue)
ZONE	Growth zone (1, 2, 3, 4)
AD	Dominant age (year) of the stand
HD	Dominant height (m) of dominant specie in the current stand
SI	Site index (m) at reference dominant age of 20 years of the stand

Value

The missing stand-level parameter: AD, HD or SI

Examples

# Example 1: Obtain Dominant Age
(AD <- get_site(DOM.SP=1, ZONE=2, HD=14, SI=10))

# Example 2: Obtain Dominant Height
(HD <- get_site(DOM.SP=1, ZONE=2, AD=25, SI=10))

# Example 3: Obtain Site Index
(SI <- get_site(DOM.SP=1, ZONE=2, AD=19, HD=13.5))
