Maintained by Claudio ZanettiniCRAN page ↗GitHub ↗Website ↗Issues ↗

Provides functions to query the FDA Global Substance Registration System (GSRS) REST API (https://gsrs.ncats.nih.gov/api/v1/). Enables programmatic access to substance records, UNII identifiers, synonyms, external codes, and chemical structures for over 170,000 registered substances.

Changes in 0.1.0

New functions

gsrs_search(): free-text and Lucene-syntax search across GSRS substances, with optional automatic pagination.
gsrs_substance(): fetch substance metadata by UNII (vectorized).
gsrs_names(): retrieve all registered names / synonyms for one or more UNIIs.
gsrs_codes(): retrieve all cross-reference codes (CAS, PubChem, ChEMBL, WHO-ATC, DrugBank, etc.) for one or more UNIIs, with optional code_system filter.
gsrs_unii_from_name(): resolve substance names to their UNII identifiers.
gsrs_structure(): fetch chemical structure data (SMILES, formula, MW, InChI, stereo info) by UNII.

From NEWS.md in the release

Install

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

install.packages("rgsrs", 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("c1au6i0/rgsrs")

Development version from c1au6i0/rgsrs. 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-rgsrs

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-rgsrs

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-rgsrs

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.
