[R-SIG-Mac] packages failed to load - Now fixed

[Prof Brian Ripley]

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.
