I'm not sure I'm "inventing my own way" of distributing R code... And I distribute it to a very limited audience.
Anyway, why not "inventing a new way" if it's more efficient than the standard one (I'm talking now in theory)?

It's a simple operation to create a package in RStudio. Not quite a
single click, but just a few.
In plain R, it's just a little more work using package.skeleton().
Really, if you are distributing R code, you should do it in the standard
way, not invent your own.
