Overview

About

Maintained by Justin WilkinsCRAN page ↗GitHub ↗Issues ↗

Provides shared worker-plan helpers, covariance utilities, model reexports, equation rendering methods, and package data used by the split 'nlmixr2' extension packages, including 'nlmixr2boot', 'nlmixr2llp', 'nlmixr2scm', and 'nlmixr2sir'. These helpers give the extension packages a common canonical raw-results schema, run-cache and seeding infrastructure, and equation-printing methods so that each extension package does not need to reimplement this shared functionality separately.

Changes in 0.3.1

Fixed rawResultsRow()'s minimization_successful column, which previously reported failure (0) for essentially every real fit. The fallback heuristic treated any non-empty fit$message as a failure signal, but nlmixr2est fit objects populate $message with the optimizer's exit text on success too (e.g. "Normal exit from bobyqa"), and never carry the $minimization_successful field the primary check looked for. The fallback now uses fit$convergence (0 = success, mirroring the underlying optimizer's ierr/status code) instead.

Install

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

install.packages("nlmixr2utils", 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("nlmixr2/nlmixr2utils")

Development version from nlmixr2/nlmixr2utils. 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-nlmixr2utils

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-nlmixr2utils

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

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