Overview

About

Maintained by Nicholas TierneyCRAN page ↗GitHub ↗Website ↗Issues ↗

A 'greta' extension for analysing transition matrices and ordinary differential equations representing dynamical systems. Provides functions for analysing transition matrices by iteration, and solving ordinary differential equations. This is an extension to the 'greta' software, Golding (2019) doi:10.21105/joss.01601.

Changes in 0.2.3

This release restores greta.dynamics to CRAN. It was archived in September

2025 as a consequence of its dependency, greta, being archived. greta 0.6.0

returned to CRAN in July 2026, which unblocks this resubmission.

Documentation fixes

The @return documentation for iterate_matrix(), iterate_dynamic_matrix() and iterate_dynamic_function() named a list element stable_state, which none of these functions actually return. The documentation now uses the real names: stable_distribution for iterate_matrix(), and stable_population for iterate_dynamic_matrix() and iterate_dynamic_function().
Added worked examples to iterate_dynamic_matrix() and iterate_dynamic_function(), which previously had none.

Now requires greta >= 0.6.0.
Removed LazyData from DESCRIPTION, as the package ships no data.

Install

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

install.packages("greta.dynamics", 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("greta-dev/greta.dynamics")

Development version from greta-dev/greta.dynamics. 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-greta.dynamics

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-greta.dynamics

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-greta.dynamics

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.
