Hi List,
I'm working with some bird tracking data, and to filter the data set, I need to
exclude points taken at the colony.
I would like to exclude coordinates from within a 500 meter radius of a point
centered on the colony.
However, as an R novice, I'm not sure how to accomplish this.
My df looks like this:
AnimalID Latitude Longitude Datetime
Any suggestions would be greatly appreciated.
