Find Local Maxima on a Map of Class 'SpatialPixelsDataFrame'

findmax finds the local maxima on a map of class SpatialPixelsDataFrame.

findmax(x)

`x`	a map of class `SpatialPixelsDataFrame` with one column

This function may be useful, among other things, to identify the local modes of the utilization distribution of an animal estimated using kernelUD.

an object of class SpatialPoints containing the x and y coordinates of the local maxima.

data(puechabonsp)

## estimates the UD
kud <- kernelUD(puechabonsp$relocs[,1])

## displays the maximum
image(kud[[1]])
points(findmax(kud[[1]]))
