Learning R for Geospatial Analysis

Summary

In this chapter, we covered the basic subjects that we are going to use in almost every operation from now on. First, you learned the fundamental methods of working with vectors, including the creation of three common types of vectors, subsetting them, and dealing with missing values in them. You also saw how dates are represented in R, and how such a representation can be useful when working with time series.
