Hi All:

If I remember correctly how R release numbers work,  R 3.5.0 would mean best practice would be to re-install all packages,  is this correct?  The Mac version has had a mechanism that does helps automate this process,  but I have a few questions as to how this works.  Specifically:

1.  In looking for packages to re-install, does it look just in the /LIbrary/Frameworks/R location for packages,  or does it look in ~/username/Library/R also?

2.  If it does look at both locations,  does the re-install then put everything into  /LIbrary/Frameworks/R or is present location maintained?

I ask because I have a lot of packages in ~/username/Library/R and want to maintain things that way, so I want to be certain that I know what will happen fi I use the built-in mechanism.
