Error message: could not find function "ojs_define"

I have just started using Quarto, but keep getting the error message - could not find function "ojs_define" when trying to define a value in an {r} code cell.

Quarto version: v0.9.276

Hi - sorry you're running into trouble.

I'm having a hard time reproducing your example. Can you please take the following code:

---
title: Hello
server:
  type: shiny
---

```{ojs}
//| panel: sidebar
vars = ["Sepal.Length", "Sepal.Width", "Petal.Length", "Petal.Width"]
viewof xcol = Inputs.select(vars, {label: "X Variable"})
viewof ycol = Inputs.select(vars, {label: "Y Variable", value: vars[1]})
viewof count = Inputs.range([1, 9], {label: "Cluster Count", step: 1, value: 3})
```

```{ojs}
//| panel: fill
Plot.plot({
  color: {
    type: "ordinal",
    scheme: "category10"
  },
  marks: [
    Plot.dot(transpose(selectedData), {
      x: xcol,
      y: ycol,
      fill: (d, i) => clusters.cluster[i],
    }),
    Plot.dot(clusters.centers, { 
      x: d => d[0],
      y: d => d[1],
      r: 10,
      stroke: "black",
      fill: (d, i) => i + 1
    }),
  ]
})
```

```{r}
#| context: server

selectedData <- reactive({
  iris[, c(input$xcol, input$ycol)]
})

clusters <- reactive({
  kmeans(selectedData(), input$count)
})

ojs_define(selectedData, clusters)
```

save it as test-shiny.qmd and then run quarto serve test-shiny.qmd on your shell? Thank you!

I realize now that it's possible you weren't running a shiny server. In that case, this should be a minimal example, which works in my local environment:

---
title: ojs_define test
format: html
---

```{ojs}
x
```

```{r}
x = c(1,2,3,4)
ojs_define(x)
```

This produces the following output for me:

Can you describe your installation and environment in more detail?

• What OS are you running?
• How did you attempt to generate the failing example?

Thank you for the example, I have now got this working.

I was expecting the function to work in R but it doesn't, it work on Render. ::face-palm:: @cscheid your example tie the missing understanding together for me. Appreciate you!
