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

[francescor]

R studio, Version 0.97.551 
SAGA from saga_2.1.0_win32.zip 
Windows 7 Profesional, Service Pack 1, 64-bit Operating System 
Privileges: "C:\\Program Files (x86)\\SAGA-GIS" requires administrator's
privileges, so I copied SAGA in that folder as administrator, but used R
from another user account. 


#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=
"C:\\Users\\reyesf\\Desktop\\Trial_with_R_calling_saga", 
                                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)
