This package intends to formalise and disseminate the macroalgae growth model originally developed by Hadley et al. (2015) and modified in subsequent works.
Getting started
Install the package with:
devtools::install_github("https://github.com/stormeyseas/macrogrow")Grow macroalgae
The main function to grow macroaglae is grow_macroalgae(). You can find a full use case in the Grow macroalgae article.
The model requires three basic sets of data to run:
- daily input vectors of environmental input drivers
- Essential: temperature, nitrate, ammonium
- Optional: surface irradience, salinity, water velocity
- a named vector of species-specific parameters, and
- a named vector of site-specific parameters
The package includes default datasets for each of these so that a simple example run can be executed immediately. These datasets are called:
- env
- a_armata (Asparagopsis armata parameters, see
for details) - site_params
Most other functions included here are called within grow_macroalgae(). There is also a checking function check_macroalgae() which is designed to take all the same parameters as grow_macroalgae() and output a report on their validity. This is to reduce the error handling contained within grow_macroalgae() and its helper functions. As a consequence, grow_macroalgae() will likely give very unhelpful errors.
