btb - Beyond the Border - Kernel Density Estimation for Urban
Geography
The kernelSmoothing() function allows you to square and
smooth geolocated data. It calculates a classical kernel
smoothing (conservative) or a geographically weighted median.
There are four major call modes of the function. The first call
mode is kernelSmoothing(obs, epsg, cellsize, bandwidth) for a
classical kernel smoothing and automatic grid. The second call
mode is kernelSmoothing(obs, epsg, cellsize, bandwidth,
quantiles) for a geographically weighted median and automatic
grid. The third call mode is kernelSmoothing(obs, epsg,
cellsize, bandwidth, centroids) for a classical kernel
smoothing and user grid. The fourth call mode is
kernelSmoothing(obs, epsg, cellsize, bandwidth, quantiles,
centroids) for a geographically weighted median and user grid.
