| Title: | Benthic Multi-Metric Index |
|---|---|
| Description: | Analysis tool for evaluating benthic multimetric indices (BENMMIs). It generates reproducible reports on the analysis of benthic data, e.g., validation and correction of species names, sample pooling, automatic conversion of genus to species names, outlier detection, benthic indicator calculation, optimization of single and multimetric indicators against a pressure gradient, and spatial aggregation of benthic indicators. One of its use cases was the development of a common benthic indicator for <https://www.ospar.org> (publication accepted by Ecological Indicators). See Van Loon et al. (2018) <doi:10.1016/j.ecolind.2017.09.029> for details. |

This function performs a complete BENMMI analysis following the
settings provided in filename.

filename |
name of the JSON file defining all analysis steps. |
tmpdir |
directory to store temporary files (for debugging only) |
browse |
load resulting report in a browser? |

Creates a BENMMI-directory structure and populates it with some relevant BENMMI-files. Users may wish to modify this directory structure and add their own data.

path |
name of an exisiting directory. This directory should be empty to prevent loss of data. If missing, a dialogue will appear. |

This function reads and checks benthos files. The format is a superset of the BEQI2-format as specified in Van Loon (2013). In addition to the BEQI2-format, the benthos-format also includes columns latitude (LAT), longitude (LONG), and sieve mesh size (MESH).

Willem van Loon, 2013. BEQI2 INPUT FORMAT
This function reads BENMMI settings files. See the package vignette
for a description of its format. Create an example file by
calling the BENMMIdir-function.
read_settings(filename)read_settings(filename)
filename |
name of BENMMI input file ( |
The function performs the following tasks:
checks the existence of filename;
reads JSON file while ignoring C-style comments;
checks avaiability of required keys in the JSON-file
checks values in JSON-file
