Overview

About

Maintained by Edlin Guerra-CastroCRAN page ↗GitHub ↗Issues ↗

The Simulation-based Sampling Protocol (SSP) is an R package designed to estimate sampling effort in studies of ecological communities. It is based on the concept of pseudo-multivariate standard error (MultSE) (Anderson & Santana-Garcon, 2015, doi:10.1111/ele.12385) and the simulation of ecological data. The theoretical background is described in Guerra-Castro et al. (2020, doi:10.1111/ecog.05284).

Changes in 1.1.0

Function adjustments

simdata() now includes the new jitter.base parameter, which allows controlled stochastic perturbations of site-level parameters. This feature increases variability among simulated communities, particularly in nested designs (e.g., sites within regions), where previous versions tended to generate unrealistically similar communities. By applying mild randomness to occurrence and abundance probabilities, simdata() produces simulated data sets with multivariate dispersion closer to empirical expectations.
The use of jitter.base is optional (default jitter.base = 0), so existing workflows remain unchanged. Users who wish to reproduce the behavior of earlier versions can simply ignore this parameter. For reproducibility, remember to use set.seed() before calling simdata().

Install

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

install.packages("SSP", 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("edlinguerra/SSP")

Development version from edlinguerra/SSP. 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-ssp

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

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-SSP

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

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

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-SSP

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
