Smooth a grid using a Gauss filter.
rsaga.filter.gauss(in.grid, out.grid, sigma, radius = ceiling(2 * sigma),
env = rsaga.env(), ...)input: SAGA GIS grid file (default file extension: .sgrd)
output: SAGA GIS grid file
numeric, >0.0001: standard deviation parameter of Gauss filter
positive integer: radius of moving window
list, setting up a SAGA geoprocessing environment as created by rsaga.env()
optional arguments to be passed to rsaga.geoprocessor(), including the env RSAGA geoprocessing environment
The type of object returned depends on the intern argument passed to the rsaga.geoprocessor(). For intern=FALSE it is a numerical error code (0: success), or otherwise (the default) a character vector with the module's console output.
