Function formatting in R Markdown documents

[duringju211]

Hi,

I want to render function code in a R Markdown document. The problem is, that I don't like the formatting of the rendered function. Is there a possibility to nicely render a function in a R Markdown document?

Here is an example of an output I would like to format. I would like to format the stringr::str_to_upper function without the ## at the beginning of the rows and without the bytecode and environment information.

---

title: "Untitled"
date: "13 7 2020"
output:
html_document:
keep_md: yes

str_to_upper

## function (string, locale = "en") 
## {
##     stri_trans_toupper(string, locale = locale)
## }
## <bytecode: 0x000001e74c8227d0>
## <environment: namespace:stringr>

Thank you very much for any help

I can partially answer this!

When creating the chunk that contains str_to_upper, you can change the chunk options to modify the output decoration. To remove the ##, use

``` {r, comment=""}
str_to_upper

If you want this as a global setting (so all chunks in document will lack the ## decoration), modify the setup chunk at the top:

```{r setup, include=FALSE}
knitr::opts_chunk$set(comment="")

I have no idea how to help with removing the bytecode or environment output, but here is where chunk options are further described?

You can try something like this:

---
output: html_document
---

some text

```{r, comment=""}
body(fun = stringr::str_to_upper)
```

some more text

This yields this for me:

Hope this helps.
