R force reinstall packages

Question

I ran the command update.packages(checkBuilt = TRUE, ask = FALSE).

However my html directories were not writable and I got a lot of:

Warning in file.create(f.tg) :
cannot create file '/usr/share/doc/R-3.0.1/html/packages.html', reason 'Permission denied'

Is there a way to force reinstall all packages now that I've fixed my permissions issues, so I get those HTML files? The code part got installed correctly, so update.packages doesn't work anymore.

Answer 1

install.packages installs a package even if it exists in your library. And of course it will be in the latest version.

Answer 2

You could run this script:

lib_loc <- "[library location]"
to_install <- unname(installed.packages(lib.loc = lib_loc)[, "Package"])
install.packages(pkgs = to_install)

If you are using the default library:

to_install <- unname(installed.packages()[, "Package"])
install.packages(pkgs = to_install)
