The plotting commands used here are lattice functions. These need to be printed to produce the plotting side effect you want. When entered at the command line printing is explicit. This doesn't happen when sourced. This is a FAQ 7.22: http://cran.r-project.org/doc/FAQ/R-FAQ.html#Why-do-lattice_002ftrellis-graphics-not-work_003f ?source does explain all of this. Solution; wrap your levelplot(...) in print(): print(levelplot(...))
