It was a permission issue for me. First, I identified where the packages were installed using installed.packages()[, c("Package", "LibPath")].

In my case, they were at /usr/lib/R/site-library and /usr/lib/R/library. Then I changed the permission of these folders by chmod (I used chmod -R 777 on the main R folder, this is my personal computer, so security is not a big concern here I think).
