Rdocumentation - page structure

Is it just me or the whole documentation document structure is not feasible? There is too much text and no easily followed code.

The detail page of the documentation is just awful. I am sorry, but it is. It should be easily followed, understandable, and should include one code example per function argument with an interactive example. Also maybe a downloadable R code. Make the code snippet editable through webpage embedded Datacamp editor (input + output).

If the document structure is easily followed, and understandable - most people won't need to post in Stack Overflow.

Start by comparing the linked RDocumentation detail pages with the reference documentation examples in the issue. No repository files, tests, or entry points are named, so identify the detail-page implementation before scoping the work. Done would require an agreed page structure and defined scope for examples, interactivity, and downloadable R code.
