I've just installed the R 3.5 version and need to access all the hundreds of packages I currently have in the 3.4 folder
"On most single-user systems (Mac, Windows, and Linux), when you upgrade to a new minor version of R (like 3.3.0 to 3.4.0), R will not find the packages, you will need to reinstall your R packages. This is an inconvenience, but the problem is obvious and it is easy to fix. If you are using a system like this, you can just reinstall your packages after upgrading R. "
That sounds fine if you have one or two packages but is there a quick script that can automate this process for large numbers?
Or is there some package that I could use with the prior version of R to facilitate?
Also can someone also explain what is the issue with just copy and pasting the folders from the file system - which is obviously the quickest method
