Answer 1

On your computer, your current library is named after your R version.

For instance, my current lib is :

.libPaths()
[1] "/home/colin/R/x86_64-pc-linux-gnu-library/3.3"

as my current R version is 3.3.

So yes, every time you'll update R, you'll face this lib problem. Note that you can set the path to your old library with .libPaths(new = "path/to/your/lib") or copy and paste your old library in the new one.
