Will need to fix before can submit to CRAN.

Can grab the last version of rgdal (1.6.7) from the CRAN archive.

'strata' function is broken.

data_strata<- strata(data[1:5, ], col_lat, col_lon)
Error in UseMethod("as_s2_geography") :
no applicable method for 'as_s2_geography' applied to an object of class "c('SpatialPolygonsDataFrame', 'SpatialPolygons', 'Spatial')"

Assume it is related to the move away from the rgdal package. But MazamaSpatialUtils rather than rgdal is used in the code.
