Simple features are a standardized way of encoding spatial vector data (points, lines, polygons) in computers. The sf package implements simple features in R, and has roughly the same capacity for spatial vector data as packages sp, rgeos, and rgdal.

Prerequisites
R and the RStudio IDE are required. See the first module on R Basics for guidance.
The libraries we will be using today are sf, dplyr and leaflet. To ensure we are all using the same version, let's install them all again on our computers.
You can install the libraries by running the following code
snippet in the console of
your RStudio IDE. Ignore any warnings regarding Rtools and if you are asked to install from sources which needs compilation, click 'No'.
install.packages(c("sf", "dplyr", "leaflet"))
Class Material
Static maps are useful for creating figures for reports and presentation. Sometimes, however, you want to interact with your data. You can use leaflet for R to overlay your data on top of interactive maps. You can think about it like Google maps with your data overlaid on top!
