geomean {geosphere} | R Documentation

## Mean location of sperhical coordinates

### Description

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

### Usage

    geomean(xy, w)

### Arguments

`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`

### Value

Ccoordinate pair (numeric)

### Author(s)

Robert J. Hijmans

### Examples

    xy <- cbind(x=c(-179,179, 177), y=c(12,14,16))
    xy
    geomean(xy)
