Hi John, thank you for that input.
It could be that the code I wrote here:
http://www.r-statistics.com/2010/04/changing-your-r-upgrading-strategy-and-the-r-code-to-do-it-on-windows/
Should be updated so every time you install a new R version, you run the
code for it to:
1) copy all packages from the old R version to the new R version library
2) update all the packages.
But I have no clue how to do step 1.
I've a clue but not the exact syntax for doing it:
a) you need to get the library directory path of your current
installation or if putting it manually;
b) list.files(path = '<path to your libraries>')
select the directories with the return of file.info();
c) save the list for processing in the newer R version;
d) in the newer version you use the list as argument to
install.packages().
All the aforementioned /caveats/ about packages not in CRAN still apply. . .
