The goal of this package is to run integrated projection models of tree species in single or multi-specific density dependence context. The simulations return the size distribution dynamics along time. These models can be completed with different harvest and disturbance models and be runned untile equilibrium.
Main methods have been developped for Kunstler et al (2020) and Guyennon et al 2023 as well as european treee species growth/survival/recruitment models.
Installation
Dependencies
This package relies on very few packages listed below, that you can install with the following code.
deps <- c('checkmate', 'cli', 'dplyr', 'here', 'Matrix',
'purrr', 'rlang', 'statmod', 'stats', 'tidyr')
for (i in deps ){
if(!require(i,character.only = TRUE))

}Stable version
You can install the matreex package from github with :
# install.packages("remotes")
remotes::install_github("gowachin/matreex")Development version
You can install the development version of {matreex} from github with :
# install.packages("remotes")
remotes::install_github("gowachin/matreex", ref = "dev")If you install the development version of this package, please check the NEWS.md or changelog regularly. The package is in active development and some changes may break your code !
Usage Guide
Getting started vignette is now available to run basic simulations with matreex package.
A second vignette about harvesting module is also available.
A third vignette about disturbance module is also available.
