volume_form_factors {MLFS}

volume_form_factors

Description

The calculation of individual tree volume using form factors, which can be defined per species, per plot, or per species and per plot

Usage

volume_form_factors(
  df,
  form_factors = NULL,
  form_factors_level = "species",
  uniform_form_factor = 0.42
)

Arguments

df

data frame with tree heights and basal areas for individual trees

form_factors

data frame with for factors for species, plot or both

form_factors_level

character, the level of specified form factors. It can be 'species', 'plot' or 'species_plot'

uniform_form_factor

a uniform form factor to be applied to all trees. If specified, it overwrites the argument 'form_factors'

Value

a data frame with calculated volume for all trees

Examples

library(MLFS)
data(data_v3)
data(form_factors)

data_v3 <- volume_form_factors(df = data_v3, form_factors = form_factors,
  form_factors_level = "species_plot")

summary(data_v3)
