  env = rsaga.env(),
  ...
)

Arguments

input: SAGA GIS grid file (default file extension: .sgrd)

out.grid

output: SAGA GIS grid file

sigma

numeric, >0.0001: standard deviation parameter of Gauss filter

radius

positive integer: radius of moving window

env

...

optional arguments to be passed to rsaga.geoprocessor(), including the env RSAGA geoprocessing environment
