Multiple Comparisons and Simultaneous Confidence Intervals
- CRAN checks, method
Method
Checks and health
CRAN runs every current package through
R CMD checkon 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.
- OKnotes on 2 of 13
- CRAN 30-day downloads, method
- 715+37% up on the 30 days before, the better direction
- Dependent packages, method
Method
Reverse dependencies
Dependent packages are other packages that list this one under
Depends,ImportsorLinkingToin theirDESCRIPTIONfile. 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
Suggestsinstall 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 28 Oct 2026, 19,572 of the 25,583 current CRAN packages had no dependent package.
- 11 more suggest it
- Test coverage, method
Method
Test coverage
Test coverage is measured by downloading each CRAN package's current source file, installing its dependencies, building it and running its tests under covr.
- Almost half of CRAN has no tests to run
- Only CRAN packages are measured. Many have no percentage, most often because the package has no tests, and that blank is a recorded outcome, not missing data.
- NOT_CRAN
- Tests run with NOT_CRAN=true, so tests that skip themselves on CRAN run here, and the figure can differ from what CRAN's own checks see.
- Current version only
- Only the current version is measured, and a new version on CRAN is measured again. Older rows are kept but never filled in later. This is one package's run.
- Never 0%
- On a package page three states stay apart: measured, no tests, and not measured. Neither of the last two is ever shown as 0%.
- No testsnothing to run
- 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 known

With this package, it is possible to compute nonparametric simultaneous confidence intervals for relative contrast effects in the unbalanced one way layout. Moreover, it computes simultaneous p-values.
Full description
With this package, it is possible to compute nonparametric simultaneous confidence intervals for relative contrast effects in the unbalanced one way layout. Moreover, it computes simultaneous p-values. The simultaneous confidence intervals can be computed using multivariate normal distribution, multivariate t-distribution with a Satterthwaite Approximation of the degree of freedom or using multivariate range preserving transformations with Logit or Probit as transformation function. 2 sample comparisons can be performed with the same methods described above. There is no assumption on the underlying distribution function, only that the data have to be at least ordinal numbers. See Konietschke et al. (2015) <doi:10.18637/jss.v064.i09> for details.

Subjects (1) Method, SubjectsMethod
Subjects and collections
Subjects are the site's own grouping of CRAN packages, found by clustering. Collections are sets of packages that communities declare, such as the tidyverse.
- Subjects
- Subjects are found by clustering the words of current CRAN packages and the packages they use. No one edits them by hand.
- Collections
- Collections are sets that communities declare, through a package that installs the set or an organization on GitHub. The site finds them by rules.
- Who made each
- Subjects are marked Site and collections Community. Subjects, collections and task views are never mixed in one list.
- The day of the data
- Subjects and collections were last worked out on 22 Oct 2026.

data/ folders when the code is analysed. Each object is described by its class, its shape and its columns, and fingerprinted so the same data can be found in other packages.data() are listed, 76,180 on CRAN and 8,045 on Bioconductor, so the list is not every file in data/.
