I'm thinking that I may include the "real" R code block in <details> block.
So you could expand and cut-and-paste with little fuss.
Thoughts?
<details>
<summary>Real full R code</summary>
```{r eval=FALSE}
code <- r"(...)"
callme::compile(code)
```
</details>

{callme} update - I'm toying with the presentation of C code chunks in the documentation.
Instead of showing the compilation of the code in C, I show the bare C code with a blue background, and then the execution of the compiled code with the normal chunk grey background.
This then allows for the C code to be syntax highlighted as C code, rather than just an R string.
Happy to hear any thoughts on usability/anything!

Hive mind: I want to generate random notes that sound ok as a melody.
Does anyone have any good references on techniques to do this?
My initial attempt to just pick a major scale and play random notes isn't a real winner. (Unsurprisingly)
Should I preference particular note intervals? Use a pentatonic scale? Some sort of Markov chain?
I have zero music theory background :)
Doing a search gets lots of LLM/ AI rubbish, which is not how I want to go.

#RStats tip for myself for function arguments:
Have 'verbosity = 0,1,2,...' as an argument rather than 'verbose = T/F'
Gives you room to tweak amount of output

Introducing {governor} for limiting rate of loop execution.
This pkg was created because I need to generate a stable framerate when outputting animations made with {nara} - ideally 30fps.
{governor} adjusts the sleep time within a loop dynamically to compensate for the time it takes to run the code so as to maintain the desired looping time.
{governor} can advise you to skip frames if work is taking too long!
Pkg also includes an alarm timer.

{nara} - finally getting to a place where I can demo what I hope to see more of in #RStats - fun, beautiful stuff!
This is 'Bubble Universe' animating and displaying in realtime with {nara}. (code included in image)
Demo code: https://github.com/coolbutuseless/narademos
{nara}: https://github.com/coolbutuseless/nara
This is my R translation of a 'Processing' demo from here: https://x.com/yuruyurau/status/1226846058728177665

#RStats hivemind: does anyone have an opinion on the various non-shiny web frameworks for R?
Beakr, plumber, ambiorix, fiery, etc
Follows up: are there any live sites using them?
