Display functions like '+' or '[' as is
knitr, r
Solution
All the credit goes to @rawr, and his comment of "set `tidy = FALSE`".
This question needed an answer.
{r, tidy=FALSE} '+'(3, 5)
`
produces
Problem
When I write code chunk in Rmd-file ```` ```{r} '+'(3,5) ``` ```` `knitr` returns html-file as ``` 3 + 5 ``` So it transforms the expression to more common format. How can I disable such transformation to keep expression as is? In comparison, the same code in Rpres-file is displayed correctly `'+'(3,5)`.
