I'm trying to set echo=FALSE as a default chunk option, but opts_chunk$set(echo = FALSE) doesn't work for notebook output.
Take this .Rmd file, for a regular R Markdown doc
---
title: "Problem with opts_chunk in html_notebook"
output: html_document
---
Set my options in this chunk:
```{r setup}
knitr::opts_chunk$set(echo = FALSE)
```
Chunk 1
```{r echo=FALSE}
cat("Is the code echoed?")
```
Chunk 2
```{r}
cat("Chunk 2. Is the code echoed?")
```
I would expect both the chunks after the setup chunk to execute without echoing the code. With output: html_document, that's what I get:
But if I change the output line to output: html_notebook, I get the following
There's another question here (R notebook: opts_chunk has no effect) with maybe the same issue, but it's not focused on echo = FALSE, and also it has no answers.
