Turning off section numbering in Bookdown output

jdlong · October 13, 2018, 2:26pm

I'm working on a book using bookdown and I'm following the pattern laid out by Hadley and @garrett in R for Data Science. In the print version of the book the Chapters are numbered, but not the subsections. In the HTML version of their book the Chapters and subchapters are both numbered. I'm trying to emulate the print output. But when I research this online I am unable to figure out how to turn off subsection numbering.

This post leads me to believe I can turn off all numbering by changing a setting

{
  "numbering": false
}

in bookdown.json. But I really would like to keep chapter numbering turned on so that figure/table numbers all work properly (i.e. continue to show the chapter number in the figure number).

I read in the Pandoc Markdown section that I could use {-} to make a subsection unnumbered. That seems like what I want to do. However I'm using the attributes section to put in section links, like this:

## My section  {#MySection}

I can't figure out how to add the - in... this doesn't work:

## My section  {-} {#MySection}

nor this:

## My section  {-, #MySection}

so I'm at a bit of a loss. How do I remove section numbers but keep chapter numbers?

Here's what R4DS looks like:

Print Version (Chapter Numbers only, no subsection numbering):

HTML Version (Chapter and subsection numbering):

# Workflow: basics

You now have some experience running R code. I didn't give you many details, but you've obviously figured out the basics, or you would've thrown this book away in frustration! Frustration is natural when you start programming in R, because it is such a stickler for punctuation, and even one character out of place will cause it to complain. But while you should expect to be a little frustrated, take comfort in that it's both typical and temporary: it happens to everyone, and the only way to get over it is to keep trying.

Before we go any further, let's make sure you've got a solid foundation in running R code, and that you know about some of the most helpful RStudio features.

## Coding basics

Let's review some basics we've so far omitted in the interests of getting you plotting as quickly as possible. You can use R as a calculator:

```{r}
1 / 200 * 30
(59 + 73 + 2) / 3
sin(pi / 2)
```

You can create new objects with `<-`:

```{r}
x <- 3 * 4

I have used this:

## My Section {-#my-section}

with success. Happy Bookdowning!

well that was easy. I feel dense for not figuring that out. Thanks for the hand holding!
