Get all previous versions of packages in RStudio Package Manager

Hi all,

As the question states - how do I programmatically in R retrieve all versions of all packages currently in a repo in RStudio Package Manager, and their package tar.gtz-bundle URLs?

Thank you

Since a repository hosted in RStudio Package Manager is just a standard R repository, you can use standard R functions to achieve this task.

Specifically, use available.packages() to list all packages, and their versions, in a repo. This function returns a matrix with columns for (among others):

  • package
  • version
  • repo URL
library(dplyr)
repos <- "https://packagemanager.rstudio.com/cran/latest"
pkgs <- available.packages(repos = repos) %>% head()
pkgs

ABCanalysis "https://packagemanager.rstudio.com/cran/latest/src/contrib"
ABCoptim    "https://packagemanager.rstudio.com/cran/latest/src/contrib"

Now you can construct the URL for any specific package, e.g:

pkgs %>% 
  as_tibble() %>% 
  mutate(
    url = paste0(Repository, "/", Package, "_", Version, ".tar.gz")
  ) %>% 
  select(url)

# A tibble: 6 x 1
  url                                                                                
  <chr>

Thanks, but I need all versions, e.g. a line for each archived version for each package.

Thanks again.
