Rmarkdown's render() + knitr's spin(): How to mix code blocks and nested items

I'm generating html- and pdf-notebooks from R-scripts using rmarkdown's function render() and knitr's function spin(). Sometimes I use nested lists and mix them with code blocks. Here is an example using rmarkdown and knitr chunk options.

#' (1) This is normal text.
#'    (a) This is normal text but indented.
#+ echo = TRUE, eval = TRUE 
print("This is code")
#'    (b) This is supposed to be normal text with the same
#'        indentation as (a). However, it will be formatted as code.
#'        By this I mean that e.g. in a pdf-notebook it will be 
#'        correctly indented but the font will be the same font as 
#'        the code.

However, everything that follows the code after list item (a) will be marked up as code as well (e.g. (b)). But what I want to achieve is to have (b) marked up as normal text and use the same indentation as (a). Is it possible to do this?

There is an internal chunk option indent that can add indentation to the chunk output. In your case, you can specify four spaces, e.g.

#+ echo = TRUE, eval = TRUE, indent = '    '

You have to use what is called The four-space rule in the documentation: http://rmarkdown.rstudio.com/authoring_pandoc_markdown.html#the-four-space-rule

So the following code works

  (1) This is normal text.

    Continued.

    (a) This is normal text but indented.

        ```{r, echo = TRUE, eval = TRUE} 
        summary(cars)
        ```

    (a) This is normal text with the same indentation as (a).

Note: There are

  • 2 Spaces infront of the (1)
  • 4 Spaces infront of each (a)
  • 8 Spaces infront of the code-block

Resulting in: enter image description here
