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)
