For most people the best thing to do is to uninstall R (see the previous Q), install the new version, copy any installed packages to the library folder in the new installation, run update.packages(checkBuilt=TRUE, ask=FALSE) in the new R and then delete anything left of the old installation. Different versions of R are quite deliberately installed in parallel folders so you can keep old versions around if you wish.

Hmisc is generating errors in R 2.8.0, so there is no binary available. 
  You could try contacting the maintainer (Charles Dupont 
<charles.dupont at vanderbilt.edu>) about it.  There's not much anyone else 
can do.  (It generates a lot of warnings in 2.7.2.)

I don't know about the Tinn-R issue, but it's probably something similar.

Upgrading is hard because R has an aggressive release schedule, and not 
all authors/maintainers of contributed packages keep up with it.  It's 
risky to use packages that generate check warnings, because they are 
often a sign of trouble to come.  (I don't know if the Hmisc errors are 
related to the warnings or not.)
