I have a dataframe with the latitude and longitudes of lakes I wanted to plot on a map of northeast USA. I'm following this

Data

lat_lon <-
  structure(list(
    LAT_DD83 = c(41.37213, 42.33589, 41.51963, 41.78447,
                 43.93213, 41.41433),
    LON_DD83 = c(
      -71.56798,-71.90907,-71.76691,
      -71.64064,-70.62131,-71.54638
    )
  ),
  class = "data.frame",
  row.names = c(NA,-6L))
