Change the assignment of json1 such that the R vector after conversion contains the numbers 1 up to 6, in ascending order. Next, call fromJSON() on json1.
Adapt the code for json2 such that it's converted to a named list with two elements: a, containing the numbers 1, 2 and 3 and b, containing the numbers 4, 5 and 6. Next, call fromJSON() on json2.

More and more of the information that data scientists are using resides on the web. Importing this data into R requires an understanding of the protocols used on the web. In this chapter, you'll get a crash course in HTTP and learn to perform your own HTTP requests from inside R.

Exercise 1: HTTP Exercise 2: Import flat files from the web Exercise 3: Secure importing Exercise 4: Downloading files Exercise 5: Import Excel files from the web Exercise 6: Downloading any file, secure or not Exercise 7: Reading a text file from the web Exercise 8: HTTP? httr! (1)Exercise 9: HTTP? httr! (2)

Importing data from the web is one thing; actually being able to extract useful information is another. Learn more about the JSON format to get one step closer to web domination.
