Alessandro,
You need to separate the put the list of input grids as a character vector e.g.:
GRIDS=c("DSM1.sgrd,DSM2.sgrd,DSM3.sgrd")

Subject: [R-sig-Geo] problem with merge grids in R+SAGA
Importance: High
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
