Learning Shiny and Shinydashboards

Hello,

I am new to Shiny and Shinydashboards and trying to locate resources to learn these including use of leaflet and sr for making maps to integrate in Shiny dashboards. which one is best for mapping leaflet or sr?

Any suggestions will be greatly appreciated!

I assume that you mean sf instead of sr.

Geocomputation with R is useful in general: Chapter 9 Making maps with R | Geocomputation with R

There are also some useful blogs and examples:
