Your Turn

Download data in ESRI Shapefile or GeoJSON format on Portland sextants (you can find the original data here)
Import the data in R using the read_sf() function from the sf package
Examine your data, making sure you can identify its geometry type, dimensions, bounding box, coordinate reference system and geometry column

This vignette from the {sf} package covers all things reading and writing geospatial data. The Geographic Data I/O chapter of the book Geocomputation with R does something similar.
