The datanovia.com webr console is pretty slick!
Like rdrr.io - this will run your code directly in it's console - or you can upload / run an R script.

Making a 'mylib' path.
1) Open terminal
2) Went to /home/michaeltbee/R
2) Did a mkdir 'mylib' - then...
3) Executed in console...

.libPaths(c("/home/michaeltbee/R/mylib"),.libPaths())

...now when I install.packages it should go there. :)

In the last script I'd used 'labs(caption...' as a plot identifier.
of the form 'rpt:nnn ~ rpttitle'

Example vimrc and Session.vim
-
Incorporate the contents of example_vimrc in your own ~/.vimrc file
If you wish to edit / review all scripts from chapter 9 in vim
try 'vim -S Session.vim'

I see a place for AI now. Things like this are a phenomenal help / aid. I think both for learning (and I think even refactoring existing code).

Here's a sample of the full / final code rewrite (with the suggested improvements).

Interesting behavior in the Code Editor! When I started typed '# Cleanup...' - the editor completed the comment and automatically added a appropriate 'rm' command! Likewise, when after this I started to write '#End...' it put out an appropriate end comment for the script!

For AddressData.R - to correctly reference a 'whole column' - drop the 'level(obj)'. Simply reference the frame-column directly.

AddressData.R - the 'camel-back' references from the book are in error. This script 07.04.AddressData.R corrects for these. Likewise, 'levels(object)' in the script outputs NULL. Drop the 'level' it runs correctly.
