Overview

About

Maintained by Adrián Cidre GonzálezCRAN page ↗Website ↗

Perform common dendrometry operations such as inventory preparing, and inventory data analysis.

Changes in 0.2.0

This new version brings new naming conventions that will be useful for sorting the package into "modules" of related functions.

silv_tree_*(): tree-level metrics (although some can be also used as stand-level using the ntrees argument).
silv_stand_*(): stand or plot-level metrics
silv_predict_*(): predictions based on models

The old functions are now deprecated and will be eliminated in a future release.

New functions

silv_density_sdi(): calculates the Stand Density Index
silv_predict_height(): estimates height from diameter, using the so-called h-d curves. The argument equation allows to choose which equations to use. Currently, only eq_hd_aitor2025() available.
silv_stand_dominant_diameter(): calculates dominant diameter using two methods:
Assman: the mean diameter of the 100 thickest trees per hectare
Weise: the quadratic mean diameter of the 20% thickest trees per hectare
eq_biomass_*(): equations to be used inside the model argument of silv_predict_biomass().

Bug Fixes

Fix an error with the validator of variable names in silviculture::Inventory S7 class.
biomass_models: some were failing because the "-" sign was parsed as an em dash.

Enhancements

Prediction functions (silv_predict_*()) will now have common arguments, and specific arguments that depend of the model used that are specified as a function (e.g. silv_predict_height(model = eq_hd_aitor2025())).
silv_volume(): it assumed diameter to be in meters. Now the diameter must be given in centimeters. An informing message was added to the function.
S7 silviculture::Inventory class now stores groups.

Deprecated functions

silv_diametric_class() deprecated in favour of silv_tree_dclass()
silv_basal_area() deprecated in favour of silv_tree_basal_area() and silv_stand_basal_area()
silv_volume() deprecated in favour of silv_tree_volume()
silv_dominant_height() deprecated in favour of silv_stand_dominant_height()
silv_lorey_height() deprecated in favour of silv_stand_lorey_height()
silv_sqrmean_diameter() deprecated in favour of silv_stand_qmean_diameter()
silv_spacing_index() deprecated in favour of silv_density_hart()
silv_ntrees_ha() deprecated in favour of silv_density_ntrees_ha()
silv_biomass() deprecated in favour of silv_predict_biomass()

From NEWS.md in the release

Install

R (CRAN)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("silviculture", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-silviculture

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-silviculture

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-silviculture

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
