We can use the function library() to get a list of all packages that are installed on our machine.

# Get the list (only names): my_pkgs <- library()$results[,1] ## Warning in library(): library ‘/usr/local/lib/R/site-library’ contains no packages # Show the results: print(paste(‘I have’, length(my_pkgs), ‘packages for R.’)) ## [1] “I have 282 packages for R.”

Alternatively, you can use the function installed.packages()

library()

installed.packages()
