[R-sig-Geo] Error in use Gaussian Filter with rsaga.geoprocessor: "Gaussian Filter: could not initialize data objects"... had status 1

[Alexander Brenning]

Hi Francesco,

just a quick reaction while I'm heading out for a few days: I haven't seem this type of error before, and the module normally works well with RSAGA, so I suspect that this is a problem with SAGA GIS dealing with your data. May I suggest that you post this on one of the SAGA GIS discussion boards on sourcefourge ( http://sourceforge.net/p/saga-gis/discussion/ ) indicating also your SAGA GIS version and attaching your raster file (or a smaller test file that causes the same error) to that post if possible. I can have a look at it myself in a week from now if it hasn't been resolved by then.

Cheers
  Alex

#Dear all,
#I cannot make rsaga.geoprocessor working to use other functions such as
gaussian filter, watershed #segmentation or hillshade.
#Did anybody encountered and solved this kind of problem?
#Thank you for reading, and maybe answering!

#For example when I run the following lines:

#Set SAGA Working Directory
rsaga.env(workspace=initialdata,
          path= "C:\\Program Files (x86)\\SAGA-GIS",
          modules="C:\\Program Files (x86)\\SAGA-GIS\\modules",
          check.libpath=TRUE)

#Gaussian Filter
rsaga.geoprocessor("grid_filter", module = 1,
                   param = list(INPUT= "C:\\Program Files
(x86)\\SAGA-GIS\\max_image_r0.25.sdat",
                                RESULT=

                                SIGMA=2 , MODE=1, RADIUS=3))


#after the following 16 lines that look fine
#R gives me the error "Gaussian Filter: could not ...."(see below)
