r=raster("foo.tif"); extent(r)=c(xmin, xmax, ymin, ymax)); writeRaster(r,"bar.tif") and now bar.tif is a geoTiff with spatial coordinates. Should also add a projection...

I see what you are saying. One more thing, so is there a way to set coordinates using the raster package? I get the impression that is what you are referring to on your original answer (I might be mistaken).

Thank you so much for your answer @Spacedman; however, I have a question regarding the last paragraph of your message. After creating a GeoTIFF file, setting up the coordinates, projection, etc, can the missing coordinates be written using exifttool_call or is there other way?
