R nb.html missing output when the output is shown inline in the RStudio
The plot I have in the Rmd file is showing in Rstudio as inline output:
But when I clicked on the preview button, the plot is missing.
Unfortunately, I am unable to create a reproducible example.

Unfortunately without reproducible example, or at least a shared document or anything, it will be hard to help and look into this.
Lots of things can happen, and it could be linked to some state of your local environment.
You could try a whole new clean project in a new RStudio session to see if caching is the culprit here. Maybe starting fresh would solve it.
If you have no specific error message or anything, I don't know what could happen. We need more to be able to start looking into this.
@cderv, Thank you so much for your reply. Is there a way I can have a log of what was run behind the scene when I press preview? Does it run knit? Maybe that way I can create a reproducible example.
I didn't create a project in RStudio. I was just creating an R notebook. I'll try creating a project.
If I start new it'll work but then after a while the same problem will happen. Let me think more on how to create a reproducible example.
Forgot to mention, if I re-run the chunk, the figure will then appear in the preview.

I don't know what RStudio IDE is really logging on that matter. When you press preview for a .Rmd with html_notebook() output, it will not run knit() as when you render with rmarkdown::render().
AFAIK notebooks works by running the preview, and then you need to execute the chunk interactively on the source mode. And when you save it will update the preview with the save content. So basically, the result of the interactive execution is saved (cached) locally by the IDE, and this is what is included in the preview.
Preview for notebook is meant for rapid development, and so it does not render the document but use this trick. This means that first time you run preview, if you have run no chunk yet in the document, you will only see the text content in the HTML and no results.

This lead me to believe this is a caching issue from the IDE. somehow the content of the chunk is seen as invalidating the result and you need to re-run the chunk interactively. This is how notebooks works as I explained above.

Yeah, it does sound like it somehow didn't save (cache) the result of interactive execution by the IDE.
Do you have any suggestion on what to check/fix for this cache issue from RStudio?
Thanks!

Unfortunately no. This could be a RStudio IDE related issue. Maybe you can try update to latest IDE if you are not using it already ?
My RStudio is pretty new 2023.06.0 Build 421 but I'll try updating to the latest. Strangely, I tried to re-run the chunk but this time it didn't work. The plot never made it to the preview. Do you happen to know where is the cache for RStudio is?

It should be local to the project.
If you could share a .nb.html or .Rmd source code, I could try on my side. Without being able to reproduce on my side, it is hard to help.
Sure. Thank you so much for helping me with this issue. Appreciate it!
I am attaching my .nb.html and .Rmd. I added.txtat the end so I can upload them here.

I can see related files in cache directory but the dates are Aug 8. even though I rerun this part of code on Aug 22.

Did you try already what is mentioned in the documentation I linked previously ?
https://bookdown.org/yihui/rmarkdown/notebook.html#chunk-output
When code is executed in the notebook, its output appears beneath the code chunk that produced it. You can clear an individual chunk’s output by clicking the X button in the upper right corner of the output, or collapse it by clicking the chevron.
It is also possible to clear or collapse all of the output in the document at once using the Collapse All Output and Clear All Output menu items available on the gear menu in the editor toolbar (Figure 3.4).
If you want to fully reset the state of the notebook, the item Restart R and Clear Output on the Run menu on the editor toolbar will do the job.
I've tried the clear individual output by clicking the X button but this doesn't work.
Clear all output also doesn't work.
I can't find how to fully reset the state of the notebook. This is all I see on my run menu
I see in your Rmd source code that you get cache=TRUE, so this means you are also activating the knitr cache feature for this one. This could be conflicting with the notebook feature maybe.
Did you try uncaching the chunk, or remove the knitr cache directory, or invalidate the cache (by modifiying the chunk a little).
To be clear, knitr cache is different than internal caching from html_notebook
