Dear R Users! I need to limit my dataset to all districts within a 100 km radius of a selected district (geographical area of interest).
I have many variables in the dataset and among them geographical coordinates of centroids, e.g.: Longitude Latitude 1 -61.68667 17.02444 2 -61.88722 17.10527 3 -61.79445 17.16333 4 -61.68667 17.02444 5 -61.72917 17.60861 ... Now, I need in the dataset only these observations (districts) which are in the radius of 100 km around the first one (-61.68667 17.02444). How to do this? Can you help me? Many thanks... -- View this message in context: http://r.789695.n4.nabble.com/Select-all-districts-within-a-100-km-radius-of-a-district-tp4733799.html Sent from the datatable-help mailing list archive at Nabble.com. _______________________________________________ datatable-help mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/datatable-help
