rcheology-package {rcheology}

Data on base packages from current and previous versions of R

Description

rcheology is a data package providing two data frames:

Details

• rcheology lists objects in versions of R from 0.50 onwards.

• Rversions lists R versions and their release dates. NB: For a more complete and "canonical" solution, see the rversions package.

The version of the rcheology package reflects the latest R version to be included in the data, e.g. 3.5.1.x contains data up to and including R 3.5.1.

An online app for data exploration is available at https://hughjonesd.shinyapps.io/rcheology/.

Where the data comes from

R versions are built using the evercran project.

Results are found from running ls(all.names = TRUE) on all installed packages. For more details, see guest-list-objects.R.

The Rversions data frame lists versions of R and release dates.

Limitations

• Functions not built on the relevant platform - e.g. Windows functions - are not included.

• R 0.60 data is not yet included.

• Functions in package tcltk are not yet included before R 2.0.0.

Historical quirks

• In 2.9.0, package Matrix was mistakenly given priority "Recommended" not "recommended" in the output of installed.packages().

• In 2.5.0, package rcompgen was given priority NA. The NEWS file records it as a recommended package.

Both these errors have been corrected in the rcheology data.
