INFCtabulate: Reproduce the tables that Tabacchi et al. published in 2011

In npuletti/ForIT: Functions to estimate tree volume and phytomass in the Italian forest inventory 2005

Description

The tables published in the work on which this package is based convey a very relevant part of the information produced: printed numbers serve as reference to verify that coded functions return expected results and, more specifically, empty spaces in the printed tables signal function applicability domain. In other words, measurement data used to estimate function coefficients values, cover only the portion of the (dbh, htot) plane where numbers are printed.

Usage

INFCtabulate(
  EPPOcode,
  quantity = "vol",
  dbh.by = 5,
  htot.by = 3,
  digits = 1,
  print_tab = T
)

Arguments

EPPOcode	tree species code defined by the EPPO database https://gd.eppo.int/search. Lookup 'INFCspecies' dataframe to retrieve recognized codes.
quantity	for each species (or species group) different quantities can be estimated. Quantity's definitions and Ids are exposed by the 'Quantities' dataframe. Default value is "vol", estimation of timber volume.
dbh.by	...
htot.by	increment value between rows (respectively columns) expressed in 'cm' (respectively 'm') for dbh (respectively total height, htot). Default 5 cm (respectively 1 m).
digits	number of decimal digits to expose in the table. Default one decimal digit.
print_tab	defaults to TRUE in order to produce a text output. If set to FALSE no printing will occur (see 'return')

Value

Function principal output is the printout of the volume or pythomass tables. If print_tab = FALSE, the function will only returns a tibble with a list column containing the tabulation of the required estimation equation/s. Using default values, tables will be identical to the corresponding published ones (or anyway similar to it) with white cells delimiting the domain of applicability of the equation.

Examples

  INFCtabulate(c("ABIAL", "ACRCA"),
                quantity = "vol",
                dbh.by = 5,
                htot.by = 3,
                digits = 1)
