To your first question, you can get your list of installed packages on Ubuntu by running "apt list --installed" and piping that to a file and copying that off somewhere safe. You'll likely have to strip that file a bit.

Then once you've got that file, on your cleanly installed system you can enumerate over that file with a bash for loop and call "apt install package"

To your second question, I'm sure we've got an R nerd around here..

I hope it will be recorded because I, too, would like to learn about
emacs.
Also, I have two questions:
1. I am running Ubuntu 18.04 LTS. When I update to ver. 20 or 22, I
would prefer to do a "clean" re-install, but I have a question. Does
that mean I must get a list of all my installed software and re-install
them one at a time after I upgrade the OS? If so, is there an easy way
for me to get the list?

2. I have been learning to use the software language R. I have a couple
of questions and I would like to hear from anyone who has R experience.

Thank You.

I am leery of the allegiances of any politician who refers to their constituents as "consumers".
