Hi, this was a great easy to follow tutorial on using leaflet with Shiny. I am particularly interested in placing shapes on maps.

Could you please give me a recommendation on this scenario:
1. I have a set of points (latitudes, longitudes) that cover a large area.
2. In this area I will place a small circle with a specified radius.
3. I want to ONLY plot those points that are within that area surrounded by the circle.

How would recommend that I determine which points are only within that circle?

Any recommendations, hints, comments, suggestions, etc., would be appreciated?

Thanks in advance.
