\BeginKnitrBlock{rmdnote}<div class="rmdnote">In most cases, the geometry column is only useful in an `sf` object.
The geometry column can only be used for creating maps and spatial operations if R 'knows' it is a spatial object, defined by a spatial package such as **sf**.
Fortunately, non-spatial data frames with a geometry list column (like `coffee_world`) can be coerced into an `sf` object as follows: `st_as_sf(coffee_world)`. </div>\EndKnitrBlock{rmdnote}
