still I am not quiet sure how to achieve this by manipulation of ID. Could you give an example, say I have 5 polygons in my shapefile shape.shp but would like to have 4 polygons, where shape[2] is merged with shape[3]. I am somewhat clueless because ID has to be of equal in length to polygons slot (in my case 5)
