I am looking to draw a radius around a lat long point, then use that buffer to filter other points that fit within it. For example:

```
#stores datasets
stores = data.frame(store_id = 1:3,
                    lat = c("40.7505","40.7502","40.6045"),
                    long = c("-73.8456","-73.8453","-73.8012")
                    )

#my location
me  = data.frame(lat = "40.7504", long = "-73.8456")

#draw a 100 meter radius around me 

#use the above result to check which points in dataset stores are within that buffer

```

Not sure how to approach this. I've worked with `over` before to intersect points and polygons but not sure how to run a similar scenario on lone points.
