packages failed to load - Now fixed
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 some time ago at https://bridgewater.wordpress.com/2010/12/21/my-favorite-r-packages-installed-with-one-command/ 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.
