tprHeight: Estimate height for given diameter w/ or w/o bark

In TapeS: Tree Taper Curves and Sorting Based on 'TapeR'

Estimate height for given diameter w/ or w/o bark

Description

Function to extract the height of given diameter w/ or w/o bark from taper curve

Usage

tprHeight(obj, Dx, bark = TRUE, cp = TRUE, mono = TRUE, Rfn = NULL)

## S4 method for signature 'tprTrees'
tprHeight(obj, Dx, bark = TRUE, cp = TRUE, mono = TRUE, Rfn = NULL)

Arguments

obj	object of class 'tprTrees'
Dx	diameter for which height is required
bark	should given diameter be considered over or under bark?
cp	cartesian product, i.e. apply all Hx to all trees, defaults to TRUE
mono	logical, defaults to true. If calibrated taper curve is non-monotonic at stem base, a support diameter is added.
Rfn	Rfn setting for residuals error matrix, defaults to list(fn="sig2"), see resVar.

Value

estimated height of given diameter

Examples

obj <- tprTrees(spp=c(1, 3, 8, 15),
                Dm=list(c(30, 28), c(30, 28), c(30, 28), c(30, 28)),
                Hm=list(c(1.3, 5), c(1.3, 5), c(1.3, 5), c(1.3, 5)),
                Ht = rep(30, 4))
tprHeight(obj, Dx = c(30, 7), bark=TRUE)
tprHeight(obj, Dx = c(30, 7), bark=FALSE)

## no cartesion product between obj and Dx, i.e. cp=FALSE
## Dx is recycled if necessary
tprHeight(obj, Dx = c(30, 7), bark=FALSE, cp=FALSE)
