Hi! I just installed the latest R 3.01.
I then wanted to update my packages.
I believe the advice given is to take the library folder from the old R version and copy it on top of (overwrite) the library folder of the new R version, in my case the library of R 2.15.2 to library of R 3.01.
When I did this, the next time I started R 3.01, I had an error message
Error in .Call("R_isMethodsDispatchOn", onOff, PACKAGE = "base") :
"R_isMethodsDispatchOn" not available for .Call() for package "base"
also the update.packages() function was 'not available'.
Where did I go wrong?
I think I will just update the packages I want rather than the whole folder and see if this works,

Copy over the base packages. This was never the advice. See e.g. http://cran.r-project.org/bin/windows/base/rw-FAQ.html#What_0027s-the-best-way-to-upgrade_003f
