camtrapviz

This package is currently under development

camtrapviz is a R and Shiny package to visualize and summarize camera trap data. It is intended for camera trap data where species have already been tagged and compiled in tables.

The Shiny application is live at https://lbbe-shiny.univ-lyon1.fr/camtrapviz/.

The package documentation website can be found at: https://lisanicvert.github.io/camtrapviz/.

Installation

To install the package, use:

devtools::install_github("https://github.com/LisaNicvert/camtrapviz", 
                         build_vignettes = TRUE)

Functions

Shiny interface

A Shiny interface run from your computer allows to analyze camera trap data interactively. To run the app, use:

run_camtrapviz()

Two example datasets are provided:

• data and cameras from the camtrapR package

• a camtrapDP datapackage from the camtraptor R package.

You can also choose data to analyze from your computer.

The Shiny app uses Shinymeta to display and export the underlying code to the Shiny app.

Data reading and formatting

The package implements functions to read and clean data (see vignettes on data import and cleaning and on data filtering).

Dataviz

There are several functions to visualize data that are illustrated below (using the example dataset from the camtrapR package).

First, you can plot the observations of each camera versus time:

You can also plot the cameras on a map:

It is also possible to plot capture event counts:

You can also plot the activity histogram and curve of the species:

For more details on plots, see the vignette on plots and the vignette on activity plots.

Data summary and analysis

Other functions allow more specific analyses:

• summarize species or cameras information (see vignette)
• get diversity indices at cameras from a species occurrence dataframe (see vignette).
