ojs inputs to R

[actuariat]

I want to pass data collected by ojs (dataojs), like [ viewof dataojs = Inputs.range(..) ] to R like define_ojs does from R to ojs.

This is crucial: but I didn't find a single mention or something.

Sorry that the information is somewhat hard to find! The explanation is here: https://quarto.org/docs/interactive/ojs/shiny.html By default, viewofs are automatically propagated to shiny, so you should be able to just refer to them by name.

Edit: here's a minimal example on shinyapps: https://jjallaire.shinyapps.io/kmeans-shiny-ojs/

Thank you for the quick answer. Sorry I wasn't clear myself. I want to replace shiny with ojs. So no shiny server, but simply to use ojs instead to gather data in an interactive way, pass it to R, make calculations and then show the results.

Your example it is quite confusing, all I get it is that I need to use input.x in order to get the collected x from ojs. But again, I do not want to use reactive (no connection to shiny at all).

Of course one can use shiny (no need for ojs), but the idea is to replace shiny in order to have a fully self-contained presentation that works locally without any server running.

So please provide a very simple .qmd with one simple rule: passing one interactive input to R. I couldn't do it, because I do not get it how ojs works.

Unfortunately, I think that is not possible with the current version of R + ojs. If you have an R function whose values depend on an OJS interactive input, then you will need that R function to execute every time the interactive input changes. As a result, you need shiny to host the execution of that R function.
