Makes for accidentally beautiful polygons but they are not retaining their hex shape. See here: https://gis.stackexchange.com/questions/37204/what-is-the-cause-of-tearing-of-polygons-artifacts-using-r-ggplot-and-geom?lq=1

Fixed issue by using "left_join" instead of "merge" when combining hex dataframe and reactive RAI dataframe. hexes.df.rai <- reactive({left_join(hexes.df, rai_species(), by = c("id" = "Camera"))})
