# BDATVOLABOR: Calculate volume under bark of a tree between height A and B In rBDAT: Implementation of BDAT Tree Taper Fortran Functions

 BDATVOLABOR R Documentation

## 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.

`BDATVOLABMR` for BDAT routine calculating volume over bark, `getVolume` for a function with a convenient english name, more options and including a bark switch.

### 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)
