predation: Predation analysis

Description Usage Arguments Value Author(s)

View source: R/predation.R

Description

This function is useful for dynamically evaluating and visualizing predator-prey interaction from Atlantis. Providing information of the predation trough time for biomass pool and for age class functional groups. This tool can helps to analyze the predatory pressure from the predator and from the prey perspective.

Usage

1
predation(biom.file, groups.csv, diet.file, age.biomass = NULL)

Arguments

biom.file

Character string with the path to biomass output file from the Atlantis simulation. Usually this output has the name "output_Model_BiomIndx.txt", were Model is the name of your Atlantis model.

groups.csv

Character string with the path to the Groups *.csv file (Atlantis input file).

diet.file

Character string with the path to the diet output file. This file contain the diets of each functional group at each recorded time step. If the Atlantis simulation is for several years, it is highly recommended a low frequency recording periodicity of this output file (toutinc). General high frequency engravings very large files and are very difficult to handle in R.

age.biomass

Character string with the path to the output file biomass by age. This is a non-standard Atlantis output file, make sure to turn on the flag "flag_age_output" in the run.prm file if you want Atlantis to write this this output file.

Value

The output of this function is a reactive html, useful for dynamically evaluating and visualizing predator-prey relationships from an Atlantis output. The outputs of the predation analysis is divided in three parts:
