Rmarkdown render () + knitr spin (): how to mix code blocks and nested elements

Question

I generate html and pdf notebooks from R scripts using the rmarkdown function render() and the knitr function spin() . Sometimes I use nested lists and mix them with blocks of code. The following is an example of using the rmarkdown and knitr .

 #' (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 eg 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 also be marked as code (for example, (b)). But I want to ensure that (b) is marked as plain text and uses the same indentation as (a). Can this be done?

Answer 1

There is an indent inner block option that can add padding to the block output. In your case, you can specify four spaces, for example.

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

Answer 2

You should 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 is

• 2 Spaces infront (1)
• 4 spaces infront of each (a)
• 8 Spaces in front of a code block

As a result:

I ran it using rmarkdown::render("test.Rmd") and this is my session information
