In this task sheet you will install and use the sf package in R to work with spatial data. The sf package implements the Simple Features standard – an open-source model for storing and accessing vector data (point, line, and polygon-based geometry) commonly used by geographic information systems. You will install the sf package and visualize spatial data provided by the United States Census Bureau in shapefile format, a file type frequently used in spatial analysis and map-making. This task sheet also uses concepts covered in GISTP 0025 - Filtering and Selecting Data with dplyr and GISTP 0026 - Mutating and Piping Data with dplyr.
