Overview

About

Maintained by Christopher Stieha4 releasesCRAN page ↗GitHub ↗

Tools to 1) simulate and visualize stochastic differential equations and 2) determine stability of equilibria using the ordered-upwind method to compute the quasi-potential.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/QPot/QPot_1.5.tar.gz"
pkgFile <- "QPot_1.5.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (1.5) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("bmarkslash7/QPot")

Development version from bmarkslash7/QPot. Installs pak first if it is not already available.
