From JSON to R

The two most important function in the jsonlite package are fromJSON() and toJSON(). Let's start with fromJSON() first. As you've seen in the video, this function can take character strings that represent JSON data. It also works if you pass a URL as a character string or the path to a local file that contains JSON data.
