Dual map view
What do you want the feature to do?
We want to control the dual map view by using the package {mapdeck}. And also, from shiny environment, we want to do it. As a example, attached is what we want to do.

Is it possible? Could you suggest any idea?? @SymbolixAU Thank you so much!
To clarify, do you want a shiny with two maps next to each other?
Yes. I imagine that
- By using shiny, there are 2 pull down buttons to choose 2 scenarios of 5.
- Then, we can compare the 2 scenarios in Kepler.gl's 3D manner.
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 for a new feature to be added to the package.
I'm not sure if this was asked, but I could imagine OP wants to use the "compare" plugin from mapbox. https://github.com/mapbox/mapbox-gl-compare
With 2 map elements next to each other and the ability to compare them with the slider.
Although the posted image would suggest just using 2 maps next to each other.
