So, is the purpose of Quarto primarily for data viz? It isn't something that for example you'd use for summary stats unless have some visual component with it?
Gracielle Higino Coach • October 8, 2024
Hi Maria! You can use Quarto for all sorts of things, including reporting summary stats. For example, I use Quarto to write scientific papers and to report survey results on a webpage for my husband's class. I'd say the purpose of Quarto is to provide you with tools to reproducibly report something.

I was wondering why David's output was showing up in the RStudio Viewer tab, but mine was not; my rendered output was going to a web-page. Our YAMLs were the same, so I wondered if it was a setting, which it was: Tools --> Global Options --> R Markdown --> Show output preview in: Viewer Pane.

I can't seem to find messages in my code chunk options. 'execute' shows up eval, echo, output, warning, error, include, cache and freeze.
Gracielle Higino Coach • March 31, 2025
Hi Alagammai! I'm not sure what you mean by "find messages in my code chunk options" as we need to write them down, not select them. In any case, there's a chance that your rendering engine is not set up as
Knitr, that's why Quarto is not recognizingmessagesas a code chunk execution option. Try typing it down anyway and rendering your document, and let us know what error messages you get!
