My periodic revisitation of “how can I include a verbatim R chunk in .rmd”? This time I am writing it down! Various proposed solutions:
From the knitr FAQ:
`r ''` ```{r label, what=ever} ```{r label, what=ever}From issue 443
`r ''````{r foo}
print('hello world!')
``````{r foo}
print('hello world!')
```From knitr example 065, involving inline R code:
```{r eval=TRUE}`r ''`
n = 10
rnorm(x)
``````{r eval=TRUE}
n = 10
rnorm(x)
```Also from knitr example 065, involving a zero-width space (copy and paste the input code into the RStudio editor to see the zero-width space after the first back tick):
` ``{r eval=TRUE}
n = 10
rnorm(n)
```` ``{r eval=TRUE}
n = 10
rnorm(n)
```From Karl Broman, involving <pre> and <code> tags:
<pre><code>```{r whatever}
data(cars)
summary(cars)
```</code></pre>```{r whatever}
data(cars)
summary(cars)
```
