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

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.
