Verbatim code chunks

[gadenbuie]

Hi @njtierney! So I was just browsing your blog's source code (you know, like a normal person) and noticed this great post wasn't showing verbatim R code chunks

njtierney.com/content/post/2018-05-16-rtip-3-rmarkdown-tricks-i-use-every-day.Rmarkdown

Lines 38 to 43 in 9ea7dd2

	In your rmarkdown code chunk, this thing
	````
	```{r}
	```
	````

To fix this, you need to add this thing (lets call it an inline R noop and save me 8 backticks)

`r ''`

to the end of the R chunk header line, i.e.

````
```{r title}`r ''`
```
````

The inline R noop breaks knitr's chunk parser so that the three+ backticked r chunk doesn't get evaluated by knitr. As always, Yihui has a blog post about it here.

Btw -- and I really hope you don't mind the intrusion -- but while I was here I noticed you have a notes on teaching draft post that is just fantastic. I have lots of outline-style posts kicking around in my head/repo/etc. where I haven't removed that draft: true and if you'll also permit me to suggest advice I wish I would listen to myself: just put it out there! Seriously. Just add a couple links where they're missing, remove or complete the few unfinished sentences, and hit publish. It doesn't need to be in paragraph form to be superbly helpful!

Heya @gadenbuie ! :)

Thanks for your kind words and feedback!

Re the backtick escape - I could not remember this trick, although I knew it existed, I find I often forget about it, and what it is, exactly. I feel like there should be an rstudio addin for this, because showing an rmarkdown chunk as is is actually a pretty common teaching case. I've actually just lodged this as an issue on the remedy package.

And double thanks for your kind comment about my teaching draft post :)

The thing is - I don't even remember writing it! I think it contains a bunch of notes from when I went through the software carpentry teaching training, from this awesome book, How learning works, and then from this talk I gave: "Rethinking teaching statistical computing"

I'll make an effort to dust off that post, and get it online, thank you so much for the push 😄
