estimate_volume: Estimate volume

In SilviaTerra/rpnc250: R implentation of USFS Research Paper NC-250: Tree Volume and Biomass Equations for the Lake States

Estimate volume

Description

Estimate volume to specified height along stem in either cubic feet or International 1/4 board feet. The equation is applied by the function apply_volume_eq.

Usage

estimate_volume(spcd, dbh, height, vol_type = c("cuft", "bdft"))

Arguments

spcd	vector of FIA species codes
dbh	vector of DBH observations in inches
height	vector of heights to which to estimate volume
vol_type	units for volume estimates, either cuft or bdft

Details

Note: this function returns gross volume (not net volume).

Value

vector of volume estimates

Examples

estimate_volume(
  spcd = c(541, 371, 95, 73),
  dbh = c(10, 11, 12, 13),
  height = c(40, 40, 24, 24),
  vol_type = "cuft"
)
