The following is sf
installation advice from Matt Herman:
Depending on your operating system and available libraries, sf
can be tricky to install the first time. The sf
website is a good place to start if you're having trouble. If you're using macOS, this is a good guide to installing the required libraries.
This data frame comes from the City of Chicago Data Portal, Boundaries - Community Areas (current). The file was last updated on December 18, 2018.
sf
documentation has helpful information on how to work with sf
objects.
