tprTrees-class {TapeS}

An S4 class to represent one or multiple trees.

Description

This class represents one or multiple trees by their biometric characteristics.

using indices i and j to subset

Usage

x[i, j, ..., drop = FALSE]

## S4 method for signature 'tprTrees'
length(x)

## S4 method for signature 'tprTrees'
show(object)

Methods (by generic)

• x[i: subsetting for class 'tprTrees'

• length(tprTrees): length function for class 'tprTrees'

• show(tprTrees): length function for class 'tprTrees'

Slots

spp

species code of trees

Dm

list of measured diameters

Hm

list of heights of measured diameters

Ht

sHt

standard deviation of total tree height, defaults to 0 for exact height measurements without error

monotone

logical indicator about monotonicity of taper curve

Examples

tprTrees() # initialise object by constructor
(tmp <- tprTrees(spp=c(1L,3L), Dm=list(c(30, 28), c(40, 38)),
                 Hm=list(c(1.3, 5), c(1.3, 5)), Ht=c(30, 40)))
