I am trying to create a PDF book using Quarto. In particular, I want to know if there is a way to specify the global chunk options, which would be used for all the chunks in all the qmd pages. The global option is
echo = TRUE
(I think this syntax is in R Markdown, not Quarto.) But only for some code chunks in some of the pages, I want to hide the code (by setting echo = FALSE). How can I do this?
In quarto documents, books or presentation, to set options like echo, eval, warning, error, include, output globally, we need to specify them under execute yaml key.
So in quarto book, to set echo to true globally, we set echo: true under execute.
_quarto.yml
project:
type: book
execute:
echo: true
book:
title: "Quarto book"
author: "Jane Doe"
date: "8/7/2022"
chapters:
- index.qmd
- intro.qmd
- summary.qmd
- references.qmd
bibliography: references.bib
format:
pdf:
documentclass: scrreprt
And setting these options locally (for some specific chunk in a specific qmd page) is same as r-markdown.
Say in my index.qmd, I can specify echo=FALSE for a chunk like this,
index.qmd
# Preface {.unnumbered}
This is a Quarto book.
