knitr syntax about knitr-examples HOT 2 OPEN

Chunk begins with 3 backticks and ends with 4, it seems like knitr is not checking for balance between the backticks as long as there is >= 3.

That's true. I just fixed the example anyway.

There are a couple of examples where there are two sequential chunks where the first is missing its closing backticks, but it is immediately followed by the start of a new chunk.

Closing backticks are not required before a new code chunk is opened. That's from Knuth's literate programming. Section 5.1.4 has more info about it: https://www.google.com/books/edition/Dynamic_Documents_with_R_and_knitr/fyIuDwAAQBAJ?hl=en&gbpv=1&bsq=%20literate%20programming

Chunks with engine and name separated by a comma

Either a comma or a space can serve as the separator.

Thank you!

Interesting, I wasn't familiar with this.
