RMarkdown chunk option `message=FALSE` does not suppress message.

ysnbiszk · October 18, 2021, 3:29pm

I noticed that RMarkdown's chunk option message=FALSE does not work on my (also on my colleague's ) environment and could not find its reason.

I tried the most simple example written in 11.7 Hide code, text output, messages, or plots | R Markdown Cookbook , and I can see its message though.

message("You will not see the message.")

I'm not sure what is going on.

I appreciate any hints or suggestions.

Here is my environment.

Windows 10

R version 4.0.5 (2021-03-31) -- "Shake and Throw"
Platform: x86_64-w64-mingw32/x64 (64-bit)

RStudio 2021.9.0.351

rmarkdown : 2.11
knitr: 1.36
rlang: 0.4.11

PS)

Also tried with R-4.1.1 or RStudio 1.4.1717 (not successful).

suppressMessages() is not the best solution.

warning=FALSE works well.

What happens if you render this document ?

---
title: "message"
output: html_document
---

```{r, message=FALSE}
message("You will not see the message.")
```

You should see no message in the output

Using the default will render a document with the message

Thank you for the advice.

Reproduced as same.

Even in html_document, inline output of the chunk show message.

So this might be a bug at inline rendering of RStudio ?

If you mean in the IDE, yes I believe this is an issue. It is track here I think:

github.com/rstudio/rstudio

RStudio 1.4.1717 and R 4.1.0 do not respect code chunk options to suppress messages/warnings/errors

bug regression r markdown

### System details RStudio Edition : Desktop RStudio Version : 1.4.1717 OS Version : macOS 11.3.1 R Version : 4.1.0 ### Steps to reproduce the problem 1. Create new R Notebook 2. Embed code chunk such as the following ```` ```{r} library(ggplot2) ggplot(data = pressure, aes(x = temperature, y = pressure)) + geom_point() + geom_smooth() ``` ```{r, echo = FALSE} library(ggplot2) ggplot(data = pressure, aes(x = temperature, y = pressure)) + geom_point() + geom_smooth() ``` ```{r, message = FALSE} library(ggplot2) ggplot(data = pressure, aes(x = temperature, y = pressure)) + geom_point() + geom_smooth() ``` ```{r, message = FALSE, warning = FALSE} library(ggplot2) ggplot(data = pressure, aes(x = temperature, y = pressure)) + geom_point() + geom_smooth() ``` ```{r, message = FALSE, warning = FALSE, error = FALSE} library(ggplot2) ggplot(data = pressure, aes(x = temperature, y = pressure)) + geom_point() + geom_smooth(blah) ``` ```{r, echo = TRUE, message = FALSE, warning = FALSE, error = FALSE} library(ggplot2) ggplot(data = pressure, aes(x = temperature, y = pressure)) + geom_point() + geom_smooth() ``` ```{r, echo = TRUE, message = FALSE, warning = FALSE, error = FALSE} library(ggplot2) ggplot(data = pressure, aes(x = temperature, y = pressure)) + geom_point() + geom_smooth(blah) ``` ```` ### Describe the problem in detail Code chunk options do not appear to be correctly evaluated in html_notebook. Of note, more than one unexpected behavior can be observed. 1. Messages and errors are not suppressed with code chunk options 2. echo = TRUE is necessary for subsequent code chunks or code will not be shown in rendered document. Code chunk options should be applied for just the specific code chunk. The behavior is as expected for html_document output (excepting the code chunk with error), when knitted. ### Describe the behavior you expected Code chunk options should be observed.  - [x] I have read the guide for [submitting good bug reports](https://github.com/rstudio/rstudio/wiki/Writing-Good-Bug-Reports). - [x] I have installed the latest version of RStudio, and confirmed that the issue still persists. - [] If I am reporting an RStudio crash, I have included a [diagnostics report](https://support.rstudio.com/hc/en-us/articles/200321257-Running-a-Diagnostics-Report). - [x] I have done my best to include a minimal, self-contained set of instructions for consistently reproducing the issue.

Issue should be fixed in next IDE release, or the one after that. A fix has been merged in RStudio repo - so this is coming !
