BDATDMRHX: Calculate diameter in height Hx over bark.

In rBDAT: Implementation of BDAT Tree Taper Fortran Functions

Calculate diameter in height Hx over bark.

Description

Function to call BDAT Fortran subroutine to calculate diameter over bark in height Hx for specified tree/s.

Usage

BDATDMRHX(BDATArtNr, D1, H1, D2, H2, H, Hx)

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]
Hx	height in tree for which diameter over bark is required

Details

conventional function interface for Fortran function BDATDMRHX. See getDiameter for more details.

Value

vector of diameters over bark

Examples

# simple call of function, with all parameters
BDATDMRHX(1, 30, 1.3, 0, 0, 25, Hx = 1.3)
# same with variables
BDATArtNr <- 1
D1 <- 30
H1 <- 1.3
D2 <- 0
H2 <- 0
H <- 25
Hx <- 1.3
BDATDMRHX(BDATArtNr = BDATArtNr, D1 = D1, H1 = H1, D2 = D2, H2 = H2, H = H, Hx = Hx)
## calling with a subset of tree characteristics
