geom_sina() and webR

[dtkaplan]

I'm keeping my eye on the possibilities for the webR system, which supports serverless R functionality in HTML documents. WebR is now coordinated with Quarto, which makes me think it could prove useful in teaching. Many packages (e.g. {dplyr}, {ggplot2}) are already available. (See https://repo.r-wasm.org/, and search for "mosaic" or "ggformula".)

Unfortunately, neither {mosaic} nor {ggformula} are available. This comes down to one function in {ggformula}, geom_sina(), which comes from the {ggforce} package which itself depends on {polyclip}. Polyclip isn't available for webR.

I think webR is promising technology for us. Perhaps we can look into moving ggforce into Suggests: and putting a conditional library(ggforce) into the code for geom_sina().

I have some other places where I do things like this, so it shouldn't be too hard to implement.

Do you know what keeps {polyclip} from being included with webR?

My impression is that some parts of the usual compiler chain for building R packages are not available yet and not expected to be available soon. {polyclip} therefore can't be compiled for WASM. In my glancing at the webR documentation, most of which goes right over my head, I saw a statement along the lines of, "Don't expect that stuff to be working anytime soon."

Digging into this a bit. It might be a bit more involved than I hoped. Some issues:

• we currently import some geoms and stats, so it isn't just gf_sina() that is a problem, we need to see if we can get it to work with geoms and stats from a non-imported package.
• Those geoms and stats also get used in additional places (like ridge plots).

So it isn't a one-liner and might require some testing/fiddling.

I was hoping this would be quick, but I may defer work on this until I have a bit more time for it.
