remove leading numbers on R scripts

[ilessing]

to be done at the same time as:

• https://github.com/UCSBCarpentry/Quarto-Project-Example/issues/15 in the Examples Repo

As discussed in our group meeting today.

we felt it doesn't make sense to number the R scripts as much as would to number Data files and other more repetitive or grouped files. R script naming would better reflect the function or purpose of the R script.

need to update screenshots too:

• fig/04-directory-tree.png (see: https://github.com/UCSBCarpentry/Reproducible-Publications-with-RStudio-Quarto/issues/14)
• fig/08-connection-error.png
• fig/08-file-connection-error.png
• fig/08-HR-external-code.png

[ilessing]

files

• fig/08-connection-error.png
• fig/08-file-connection-error.png

are no longer in use. they are not referenced in the lessons

so I'm doing:

git rm fig/08-file-connection-error.png
git rm fig/08-connection-error.png

I think this is done. I hope I didn't miss anything.
