Hi all, I am starting to learn spatial analysis using R. Do anyone know if the attribute data in a spatialpolygonsdataframe can contain multiple observations within the same polygon? To be specific, I have a spatialpolygonsdataframe that contain USA county polygons and the relevant attribute data contains the relevant state,county and FIPs. And I also have another data-frame that contains weather features by year by county (For example there are yearly average temperature for each county) . How can I join the spatialpolygondataframe with the weather data so that the resulted attribute table in the joint spatialpolygonsdataframe can contain *multiple-year* weather features within each county? Thank you very much for any kindly help. Meta [[alternative HTML version deleted]]
