Summary

In this chapter, we learned about the world's greatest analytics platform, R. We started from the beginning and built a foundation, and will now explore R further, based on the knowledge gained in this chapter. By now, you have become well versed in the basics of R (which, paradoxically, is the hardest part).You now know how to:

• Use R as a big calculator to do arithmetic
• Make vectors, operate on them, and subset them expressively
• Load data from disk
• Install packages

You have by no means finished learning about R; indeed, we have gone over mostly just the basics. However, we have enough to continue ahead, and you'll pick up more along the way. Onward to statistics land!
