Overview

About

Maintained by Stanislas Mahussi GandahoFirst published 2026-07-161 releasesCRAN page ↗GitHub ↗

An integrated, tidyverse-friendly workflow for camera trap data in wildlife monitoring and ecological research. Reads and edits media metadata, filters independent detections, analyses activity patterns and species diversity, and estimates species density or abundance with several methods, including the random encounter model, camera-trap distance sampling, time-to-event, space-to-event, and the random encounter and staying-time model (see Rowcliffe et al. (2008) doi:10.1111/j.1365-2664.2008.01473.x, Howe et al. (2017) doi:10.1111/2041-210X.12790, Nakashima et al. (2018) doi:10.1111/1365-2664.13059, and Moeller et al. (2018) doi:10.1002/ecs2.2331).

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)

install.packages("ct", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("stangandaho/ct")

Development version from stangandaho/ct. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-ct

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-ct

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager
