Are you sure you have the right extents? Try g.region rast=puertoRico
then display again. Also, you could try: r.info puertoRico to get the raster statistics and extent and check if it makes sense. Are you on Windows? The output below shows that the map is being written to a PNG output file. Did you check that file?
