In repo.data: R Repository Data

repo.data

The goal of repo.data is to make repository data accessible. Mainly it consumes existing data but the idea is to also generate it.

When a function is specific of a repository it will start with its name: cran_ or bioc_.

From CRAN:

install.packages("repo.data")

You can install the development version of repo.data like so:

remotes::install_github("llrs/repo.data")

We can get a data.frame of all packages on CRAN archive:

library(repo.data)
ca <- cran_archive()
#> Warning: There are 4 packages both archived and published
#> This indicate manual CRAN intervention.
head(ca)
#>         Package            Datetime Version   User   Size   Status
#> 1            A3 2013-02-07 10:00:29   0.9.1 hornik  45252 archived

#> 6          aaMI 2005-06-24 17:55:17   1.0-0   root   2968 archived

We can also check CRAN comments about the packages on its archive:

cc <- cran_comments()
#> Retrieving comments, this might take a bit.
#> Caching results to be faster next call in this session.
head(cc)
#>    package
#> 1       A3
#> 2    aaSEA
#> 3      aba
#> 4   abbyyR
#> 5   abcADM
#> 6 abcdeFBA
#>                                                                          comment

Or estimate the last date of update of our packages, by the information on the session info or a data.frame:

cran_session(session = sessionInfo())

#> Maybe they were not on CRAN?

ip <- installed.packages()
cran_date(ip)
