[R] installing packages from a directory on the computer

[Peter Ehlers]

Okay, Subramanian S, try this:

pkgs <- c("pkg1", "pkg2", "pkg3")
install.packages(pkgs, repos = NULL,
                  contriburl = "file:///c:/r/repos/2.12",
                  dependencies = TRUE)

where I've got zipfiles in c:/r/repos/2.12.

Comments:
1. Note the 3 slashes after "file:".
2. You will also have to copy the file PACKAGES into
    your download folder.
3. Specify "lib=" if you don't want to install into the
    default directory.
4. You may get warnings about unavailable packages.
