I recentlry tried to upgrade to 2.8.0. I ended up uninstalling 2.7.2 and

That's a matter of taste. 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.
The problem that I had is the library directroy in 2.8.0 was almost identical
to 2.7.2. No folders that were different from the installation with 2.8.0 yet I
know that I have installed packages. So I am not sure what to copy.
I also uninstalled Tinn-R and tried to reinstall it now I am getting the ".trpaths
not found" error. So I tried to configure the Tinn-R installation and I get:
Warning in install.packages("Hmisc") :
argument 'lib' is missing: using 'F:\Users\Kevin\Documents/R/win-library/2.8'
--- Please select a CRAN mirror for use in this session ---
Warning message:
package ‘Hmisc’ is not available
Hmisc is generating errors in R 2.8.0, so there is no binary available.
You could try contacting the maintainer (Charles Dupont
<[EMAIL PROTECTED]>) 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.)
