It's really odd that people blog about their own inefficient scripts
rather than read the R documentation.
Because this scripts checks (very inefficiently) if a package is
already installed, it would not solve the problem discussed in this
thread. And install.packages() takes a vector of packages, and
'survival' is a recommended package and should always be installed.
Because people have differing needs there are different ways to do
this. But the ideas of
http://cran.r-project.org/bin/windows/base/rw-FAQ.html#What_0027s-the-best-way-to-upgrade_003f
suit many.

There's a handy script to automate the update process that I came across

When you run the script, it will automatically install the libraries that
you set up in the script. When you run it, it will install into the first
location in .libPaths(). If you want packages installed in ~/Library/R...,
then you need to check the "Default Library Paths" option in
R-->Preferences-->Startup. Alternatively, you could supply the lib= argument
to the install.packages() call. With a little extra code, you could even
define the install location for each package individually.
Here's a shortened version:
