How to display verbatim inline r code with backticks using Rmarkdown?
Here is a trick that I use. First, note \x60
is `
:
> cat('\x60', '\n')
`
Then you write
`r '\x60r foo+bar\x60'`
which will give you `r foo+bar`
in the markdown output, but that will become r foo+bar
in the HTML output, so you need to protect the backticks in markdown, using two (or more) backticks. Then you end up with this hairball:
`` `r '\x60r foo+bar\x60'` ``
Your own solution is good, but I'd just define
rinline <- function(code) {
sprintf('``` `r %s` ```', code)
}
Also see this post for another trick.
To anyone looking at this now, you may want to check out the more recent solution here: embed Rmarkdown without knitr evaluation
Essentially you can do:
Some R code inline : `r knitr::inline_expr("2+2")`
I'm guessing that the functionality describe above has been added to knitr directly but it saves us defining the function ourselves.
