I've updated the underlying mapbox.js to the latest v1.10.0, and deck.gl to v8.1.6, so please try this and see if the error persists? ```r remotes::install_github("SymbolixAU/mapbox") ``` Other than this, I...

Unfortunately neither [pointcloud](https://github.com/visgl/deck.gl/blob/master/docs/layers/point-cloud-layer.md#data-accessors) nor [column](https://github.com/visgl/deck.gl/blob/master/docs/layers/column-layer.md#data-accessors) have a `getRadius` data accessor, so it's not possible at the moment. But this is something you/we could ask over at [deck.gl](https://github.com/visgl/deck.gl)

for testing, try the `add_grid()` layer with `gpu_aggregation = FALSE` argument ```r remotes::install_github("SymbolixAU/mapdeck", ref = "issue325") ```

Have you installed the dev version using the `remotes::install_github("SymbolixAU/mapdeck", ref = "issue325")` code I gave? This works for me ```r mapdeck() %>% add_grid( data = roads , gpu_aggregation = FALSE...

You may need to re-start your R session before installing it. And also "Try removing 'C:/Users/User/Documents/R/win-library/3.6/00LOCK-mapdeck'"

Then I'm not sure how much I can help as I think this is related to the hardware and / or browser on the mobile device.

This might get solved in Deck.gl v8.3 - https://github.com/visgl/deck.gl/issues/4998#issuecomment-706298106 When 8.3 is release I'll merge it into here and we / you can test this again.

To clarify, do you want a shiny with two maps next to each other?

I think you're asking for help with building a shiny, rather than there being an issue with mapdeck. This issue page is for reporting issues with the package, or asking...
