Details

The number of packages on CRAN and the R version can be obtained for selected dates in the past from the dataset cran_history.

Note: Previously, these functions could obtain the number of packages on CRAN and the then current R version also for past dates by using snapshots from Microsoft's MRAN. However, MRAN shut down on 1 July 2023 such that this functionality is no longer available.
