This opens the file for reading by R's general reading and writing routines. The shapefile function handles all this so you don't pass it a file object, you pass it the path as a string.

The rgdal package offers the readOGR function that allows to read shapefile using the following syntax. Please try th following command to understand how this object works:. The basic plot function knows how to plot a geospatial object. It is totally possible and advised imo to build the map with ggplot2.

However, ggplot2 takes as input data frames, not geospatial data. In later episodes, we will learn how to work with raster and vector data together and combine them into a single plot. We will use the sf package to work with vector data in R.

Notice that the rgdal package automatically loads when sf is loaded. We will also use the raster package, which has been loaded in previous episodes, so we can explore raster and vector spatial metadata using similar commands. Make sure you have the sf library loaded. The first shapefile that we will open contains the boundary of our study area or our Area Of Interest or AOI, hence the name aoiBoundary.
