My RStudio session is crushing when trying to draw an rgl 3d plot using knitr in ioslides html presentation. Any ideas how to prevent it?

My chunk:

```{r setup, results='asis'}
library(knitr)
library(rgl)
knit_hooks$set(webgl = hook_webgl)
```

```{R, testgl, webgl=TRUE, cache=FALSE}
x <- sort(rnorm(1000))
y <- rnorm(1000)
z <- rnorm(1000) + atan2(x,y)
plot3d(x, y, z, col=rainbow(1000))
```

Edit

This error occurs for:

You probably need to update RStudio. I had it crash for a while, I think because their WebGL implementation wasn't working; now it runs fine (though it doesn't display WebGL, I have to view the output in my browser for that).

Edited a couple of years later: I haven't seen a crash in a long time, and rgl (displayed by calling rglwidget()) now displays fine in RStudio.

  • I think you'll need to give enough details for someone to reproduce the crash. Post a complete .Rmd document, and list sessionInfo from R, as well as the RStudio version number. – user2554330 Sep 09 '15 at 10:47
