BDATVOLABOR: Calculate volume under bark of a tree between height A and B

In rBDAT: Implementation of BDAT Tree Taper Fortran Functions

Calculate volume under bark of a tree between height A and B

Description

BDAT-Function to get wood volume under bark of one or many trees of a section between height A and height B

Usage

BDATVOLABOR(BDATArtNr, D1, H1 = 1.3, D2 = 0, H2 = 0, H, A, B, SekLng = 2)

Arguments

BDATArtNr	numeric vector of species code; see getSpeciesCode
D1	first measured diameter of tree [cm], e.g. diameter in breast height
H1	measurement height of D1 [m]
D2	second measured diameter of tree, see buildTree for details on how to specify different taper forms
H2	measurement height of D2, see buildTree for details on how to specify different taper forms
H	total tree height [m]
A	lower height of section for which volume is required [m]
B	upper height of section for which volume is required [m]
SekLng	length of section over which the integral of taper form should be applied, defaults to 2.0m

Details

wood volume is calculated using BDAT Fortran routines.

Value

vector of same length as input variables transformed into a data.frame, returning the required wood volume in cubic meter.

Examples

## simple call of function, with all parameters
BDATVOLABOR(1, 30, 1.3, 0, 0, 25, .25, 5.25, 2.0)
BDATArtNr <- 1
D1 <- 30
H1 <- 1.3
D2 <- 0
H2 <- 0
H <- 25
A <- 1
B <- 10

## same with variables
BDATVOLABOR(BDATArtNr = BDATArtNr, D1 = D1, H1 = H1, D2 = D2, H2 = H2, H = H, A = A, B = B)

## calling with a subset of tree characteristics
## german species names, abbreviated
BDATVOLABOR(getSpeciesCode(c("Fi", "Bu")), 30, 0, 0, 0, H = 25, A = 0, B = 25)
## english abbreviation
BDATVOLABOR(getSpeciesCode(c("NS", "BE")), 30, 0, 0, 0, H = 25, A = 0, B = 25)
