In rcheology: Data on Base Packages for Current and Previous Versions of R

rcheology

A data package which lists every command in base R packages since R version 0.62.3.

The latest R version covered is 4.3.1.

You can view the data online in a Shiny app.

Installing

From r-universe:

install.packages('rcheology', repos = c('https://hughjonesd.r-universe.dev', 
                    'https://cloud.r-project.org'))

From CRAN:

install.packages('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.

Do it yourself

• Install and start docker.
• Run host-run-on-evercran.sh.
