Depends on the update.  To move from 1.1.1 to 1.2.0 or later, yes,
you need to re-install many of the packages as the header files changed
with the new memory management.  I found it hard to guess correctly
which ones, and re-installed all of them.

When I updated our installations on Friday, I installed 1.3.0 over where
1.3.0 had been installed, ran update.packages() and then looked for
files in the installation tree over a day old and deleted a few (the demos
directory for example).

If you have not updated at all since 1.1.1, update.packages() will
re-install all the current packages, as the oldest on CRAN is dated Jan
11, after 1.2.0 came out.  You will then want to REMOVE survival5 and
integrate, which are obselete.
