I am trying to use geom_spatial_polygon but regardless of the dataset I use, if my data is numeric, integer, factor or character, or if I start the plot with basemap() or ggplot() I receive the following error: Problem while converting geom to
grob.
ℹ Error occurred in the 1st layer.
Caused by error in as.vector():
! cannot coerce type 'closure' to vector of type 'character'
I would really appreciate any advice on how to fix this as I have been stuck here for over a week!
