Hello to everybody, I´m trying to use the SAGA tool "Add Grid Values to Points" in R using the RSAGA package ("shapes_grid", 0) but there is an error message I can`t figure out.:
> rsaga.geoprocessor("shapes_grid",0, list(SHAPES="test.shp", > GRIDS=list("slope.sgrd", "aspect.sgrd"), RESULT="add_grid.shp", INTERPOL=0), env=myenv) SAGA CMD 2.0.3 library path: C:/Programme/saga_vc/modules library name: shapes_grid module name : Add Grid Values to Points author : (c) 2003 by O.Conrad error: executing module [Add Grid Values to Points] Usage: -silent -SHAPES <str> -GRIDS <str> -RESULT <str> [-INTERPOL <num>] -SHAPES:<str> Points Shapes (input) -GRIDS:<str> Grids Grid list (input) -RESULT:<str> Result Shapes (output) -INTERPOL:<num> Interpolation Choice Available Choices: [0] Nearest Neighbor [1] Bilinear Interpolation [2] Inverse Distance Interpolation [3] Bicubic Spline Interpolation [4] B-Spline Interpolation 'add_grid.shp' is not a correct numeric value for option 'INTERPOL'. I can`t explain why R is trying to understand the expression "add_grid.shp" as the Interpolationmethod even though it is previous to the INTERPOL expression in the command. Any ideas? Thank`s a lot.
