hfromd: Estimate tree height above ground from diameters

In JohannesRahlf/taperNO:

Estimate tree height above ground from diameters

Description

Estimates tree height above ground from diameters using optimization of the taper function.

Usage

hfromd(d, h, sp = "spruce", output = "h", grd_search = F)

Arguments

d	diameters (cm).
h	height above ground of diameter measurements (m).
sp	species
output	output from optimization: 'h' outputs the tree height,'d' diameter at breast height, 'all' result of optim.
grd_search	if TRUE optimization is run on a matrix of initial parameters. The result of the best fit is returned. Might give better result at cost of performance.

Value

Tree height above ground (m).

Examples

hfromd(d=c(39,27),h=c(2,7),sp="birch")
