问题
I'm trying to write a memo on R Markdown syntax and as such I'd like to include in the document's output the R Markdown code and the output.
To be clear, I'd like the output to look something like:
~~~~~~~~~~~~~~~~~~
Including the following code chunk in the document:
```{r, eval=FALSE}
summary(cars)
```
will produce the following output:
summary(cars)
~~~~~~~~~~~~~~~~~~
I'm failing to escape the ``` and the {r, eval=FALSE}.
回答1:
Maybe if you evaluate this:
```{r comment=NA}
cat("```{r, eval=FALSE}\nsummary(cars)\n```")
```
