[R-sig-Geo] problem with merge grids in R+SAGA

[alessandro.montaghi at unifi.it]

Hi All

when I use this function with R and SAGA:

rsaga.get.usage("grid_tools", 3)
rsaga.geoprocessor(lib="grid_tools", module=3,  
param=list(GRIDS="DSM1.sgrd,DSM2.sgrd,DSM3.sgrd",GRID_TARGET="DSM.sgrd",TYPE=7, INTERPOL=2,  
OVERLAP=0))

I have this problem

SAGA CMD 2.0.3
library path:   C:\Windows/modules
library name:   grid_tools
module name :   Merging
author      :   (c) 2003 by O.Conrad

Load grid: DSM1.sgrd,DSM2.sgrd,DSM3.sgrd...

failed

error: Grid file could not be opened.

error: input file [DSM1.sgrd,DSM2.sgrd,DSM3.sgrd]

error: empty input list [GRIDS]

error: executing module [Merging]


I don't understand very well where is the problem of the code.

thanks for help

Ale
