Hiding code in jupiter in R

Question

I would like to try to produce reports (pdf and probably html) in jupyter using R kernel. However, I would like to hide code in two ways, depending on audience:

1. all code cells
2. some code cells

When I have looked for this I found answers for python kernel. Is there a way to this in R (no python code)?

Answer 1

So I have started to combine python's answer: How to hide code from cells in ipython notebook visualized with nbviewer? with How to render LaTeX / HTML in Jupyter (R)? and it works. If one puts the following code in a cell, will get a button for hiding code. From here I think I know where to start.

library(IRdisplay)

display_html(
'<script>  
code_show=true; 
function code_toggle() {
  if (code_show){
    $(\'div.input\').hide();
  } else {
    $(\'div.input\').show();
  }
  code_show = !code_show
}  
$( document ).ready(code_toggle);
</script>
  <form action="javascript:code_toggle()">
    <input type="submit" value="Click here to toggle on/off the raw code.">
 </form>'
)

Answer 2

As you're talking about making HTML and PDF reports, you can do this by using a custom template with nbconvert, and using that to hide cells. This will work for any notebook, independent of the kernel you use.
