Create List of Installed Packages in R (Example)

In this article, I’ll explain how to get the names of all installed packages of a user in the R programming language.

The content of the page looks as follows:

Let’s jump right to the exemplifying R code:

Example: Return List of Installed Packages & Version Using installed.packages() Function

This example explains how to get the names of all installed add-on packages in R.

For this, we can use the installed.packages() function as shown below

my_packages <- as.data.frame(installed.packages()[ , c(1, 3:4)])            # Apply installed.packages()
my_packages <- my_packages[is.na(my_packages$Priority), 1:2, drop = FALSE]  # Keep NA rows
rownames(my_packages) <- NULL                                               # Rename rows
head(my_packages)                                                           # First six packages

In Table 1 you can see that we have created a data frame containing all packages and versions of our installed packages.
