The goal of batata is to help R users manage R packages removals. For example, imagine you’re attending tomorrow an R meet up in which you’ll experiment many packages that you don’t want to keep. By the end of the meet up, you’ll have to remember each installed package, its name (trust me, packages’ names may be complicated). Further, each installed package comes with a bunch of dependency which makes the operations more complicated. Using the batata package, you can just run rm_today_packages() (one of many other functions), and you’re clean for today. Before removing the packages, batata will prompt you to confirm your decision (which adds a certain degree of security), you can also run today_packages() to check all the today installed packages before making a decision.

batata takes into account the modification time of the packages instead of the birth time. As such, if you decide to update a package to a newer version, batata will consider it as a new package (which is technically true as a new package will be installed).


You can install the stable version of batata from CRAN with:


You can install the development version of batata from Github




The fresh_start() function removes all your installed R packages. Particularly useful when moving from an R version to another. This function is quite dangerous, so you’ll be prompted twice to make sure that you’re absolutely certain to run it.

today_packages() and rm_today_packages()

today_packages() displays all the packages installed the day you’re running that function and in parallel, rm_today_packages() removes the corresponding packages.

yesterday_packages() and rm_yesterday_packages()

yesterday_packages() displays all the packages installed the day before you’re running that function and in parallel, rm_yesterday_packages() removes the corresponding packages.

since_packages() and rm_since_packages()

since_packages() displays the packages that you’ve installed according to a specific date. It has two argument:

  • date: the considered date in yyyy-mm-dd format ;
  • position: whether to display the installed packages at that date, before that date or after that date.

rm_since_package() works similarly except that it removes the packages instead of displaying them.

latest_packages() and rm_latest_packages()

Suppose you want to check out the last 10 packages that you’ve installed, or, maybe you want to display the last installed package:


# The 10 last installed packages

latest_packages(n = 10)

# The last package installed 

latest_packages(n = 1)
