Hands-On Exploratory Data Analysis with R

Getting data into R from web APIs using the httr R package

We need to implement the following steps to extract data using the httr package in R workspace:

First, we load the httr package:

library(httr)

We then call GET function and pass it as a URL:

r <- GET("http://httpbin.org/get")

This gives us a response object that can be processed further for data. To start with, we can print out the response object to get some information about the data:

>rResponse [http://httpbin.org/get]  Date: 2019-01-18 03:45  Status: 200  Content-Type: application/json  Size: 326 B{  "args": {},   "headers": {    "Accept": "application/json, text/xml, application/xml, */*",     "Accept-Encoding": "gzip, deflate",     "Connection": "close",     "Host": "httpbin.org",  "User-Agent": ...
