Details

Data on the number of packages on CRAN between 2001-06-21 and 2014-04-13 is obtained from CRANpackages from the package Ecdat. This data was collected by John Fox and Spencer Graves. Intervals between data points are irregularly spaced. These data are marked with "John Fox" or "Spencer Graves" in the column source. They are licenced under GPL-2/GPL-3.

Data between 2014-10-01 and 2023-03-06 was collected by the package author from CRAN snapshots on Microsoft's MRAN, which was retired on 1 July 2023. Data was collected on the first day of each quarter. These data are marked with "MRAN" in the column source.

Newer data has been collected in irregular intervals using the functions n_available_packages() and available_r_version(). These data are marked with "CRAN" in the column source.
