title: R - How do I draw a radius around a point and use that result to filter other points?
body: <p>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:</p>
  
  <pre><code>#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
  </code></pre>
  
  <p>Not sure how to approach this. I've worked with <code>over</code> before to intersect points and polygons but not sure how to run a similar scenario on lone points.</p>
