Summary
In this chapter, we covered the basic methods for working with raster data in R. We now know how to import and export raster data to and from the R environment, how to examine the raster objects at hand, and how to perform simple calculations to modify these objects. We also covered several ways to visually display raster data in R.
The next chapter is going to be very similar in structure and purpose to the present one; it's just that we are going to cover the other main type of spatial data—vector layers.
