A Null Model Algorithm to Analyze Cyclical Data in Ecology.

rosario

The rosario package provides tools to quantify and visualize temporal niche overlap using Pianka and Czekanowski indices, and to simulate null models with the ROSARIO algorithm (Castro-Arellano et al. 2010).

Installation

You can install the development version of rosario from GitHub with:

# Install devtools if you don't have it
install.packages("devtools")

# Install commecometrics from GitHub
devtools::install_github("mariahm1995/rosario")

You can also get the official release version from CRAN

install.packages("rosario")

Example

This is a basic example which shows you how to solve a common problem:

library(rosario)

# Example data
ex1

# Assemblage-wide overlap
temp_overlap(ex1, method = "pianka")

# Null model test
nm <- get_null_model(ex1, method = "pianka", nsim = 200, parallel = FALSE)
nm$p_value

# Visualize ROSARIO patterns
plot_rosario(ex1[1, ], cols = 5)
