Method
Checks and health
CRAN runs every current package through R CMD check on a set of machines and publishes a result for each one. The health shown on a package page comes from these results alone.
- Problems
- Notes alone never count against a package, but a warning, an error or a failure on any platform is a problem. Open CRAN deadlines are a fact of their own, shown as a clock after the mark, so the mark always says what the checks found.
- Checks only
- Health reflects CRAN's check results and nothing else. Even a package with no tests, no coverage or no recent release can have every platform OK.
- Once a day
- Results are collected once a day from files CRAN publishes. Each platform is one machine set-up, named by its R version, operating system, architecture and compiler, such as r-devel-linux-x86_64-fedora-clang.
- Platforms counted
- The 13 in 3 of 13 is the number of platform rows CRAN published for that package on the day of collection. The set of machines changes over time, so the number is not fixed, and a package missing from a platform counts as neither passing nor failing there.

- Dependent packages, method
Method
Reverse dependencies
Dependent packages are other packages that list this one under Depends, Imports or LinkingTo in their DESCRIPTION file. Those fields list the packages a package needs to install, so dependents break if this one is archived or broken.
- As declared
- The counts follow the declarations as written, not whether a package uses the other one when it runs.
- Suggests apart
- Packages that list this one only under Suggests install and run without it, and use it for tests, examples or an optional feature. They are counted as Suggested by, never among the dependents, and a package that also lists it under one of the three fields is a dependent and is not counted again.
- Zero
- Zero dependents means no current CRAN package declares a need for this one, though some may suggest it. On 26 Oct 2026, 19,530 of the 25,531 current CRAN packages had no dependent package.

- Advisories, method
Method
Security advisories
Advisories come from the R Consortium advisory database, a community record of security problems in R packages, as OSV publishes it.
- The copy
- The record is read once a day. The data is published under the Apache License 2.0 and is credited on the advisories list.
- Box under the name
- Under the package's name, a box names any advisory that affects the current release, with its fix or that there is none.
- Ranges
- Advisories state ranges, such as from 0.9.12 up to but not including 1.8.8. Each range is checked against every version CRAN has published, using the version rules R itself uses, so a release that came out after the advisory was written is still caught by its range.
- Not the package
- The rating is for the library flaw itself, not for how exposed the R package is, and it is never added up into a figure for the package.
- None publishedfor Bioconductor

Tests
Method, Tests Method Test coverage is measured by downloading each CRAN package's current source file, installing its dependencies, building it and running its tests under covr.Test coverage
Test coverage is measured for CRAN packages only. Nothing is known for Bioconductor packages, which is not the same as no coverage.
