geomean

Mean location of sperhical coordinates

mean location for spherical (longitude/latitude) coordinates that deals with the angularity. I.e., the mean of longitudes -179 and 178 is 179.5

geomean(xy, w)

`xy`	matrix with two columns (longitude/latitude), or a SpatialPoints or SpatialPolygons object with a longitude/latitude CRS
`w`	weights (vector of numeric values, with a length that is equal to the number of spatial features in `x`

Ccoordinate pair (numeric)
