Creating contours with Geospatial Modelling Environment

[المشرف العام]

I'm trying to create contours from a raster using GME but continually get this error message regardless of what I try in terms of moving the input raster around or output destination... any thoughts?

• Thanks!

Found R here: C:\Program Files\R\R-3.2.1\binTo switch to a different version of R use the 'Set R executable folder' item in the File menu, or use the r.setpath() command.

contour(in="E:\GIS\TownGIS.gdb!DEM_20m", out="E:\GIS\TownGIS.gdb!contour25m", levels="25", band=1);

Error: The specified workspace does not exist. Cannot open raster dataset: E:\GIS\TownGIS.gdb!DEM_20m

Error: The command text could not be interpreted. Please check the syntax of the command.

Error: An important error has occurred. Please include the information below if you submit a query about this error.The XY domain on the spatial reference is not set or invalid.
