Sep 8, 2019 at 6:33 comment added Jeff You're right @Spacedman, I get that list.files() returns characters -- but evidently I misunderstood how to loop through the resulting list to load() the files to manipulate them. I see a lot of examples of binding text/csv files to dataframes, though.
Sep 6, 2019 at 15:25 comment added Spacedman The error is saying the first argument is a character value. The thing you have written as regionX-yearY is evaluating to a character value. Why? Load one in and print it out to check. Its not a SpatialPolygonsDataFrame. Of course looping over files with list.files creates characters, that's what list.files does.
