![]() If you paste this into Chome then you get something back like this: ![]() Here is a fully functional URL you can paste into your browser: We need 1) the base Google URL for the Geocoding service, 2) the format of the desired output (XML or JSON), 3) and address for which we want to find the latitude and longitude, and 4) the API key we create at the Google API service. So one way to do this is to create a URL according to the specification given in the Google Geocoding documentation. If you are currently taking one of my classes I probably have arranged for cloud credits that you can use to do Google Geocoding for free. You have to sign up for an account and get an API key. They used to provide free access to this service but no more. Let’s run through an example of using the GeoCoding API with Google. ![]() # 8 8 Bangladesh 172,180,722 2.17% National population clock # 4 4 Indonesia 269,603,400 3.40% National annual projection # 3 3 United States 333,191,720 4.20% National population clock # Use read_html to fetch the webpage url % html_nodes( xpath= '/html/body/div/div/div/div/table') %>% html_table() # We have to get the first element of the list. We can use the resulting path to directly access the table without first having to first pull out all tables and then trying to find the right one Once you highlight the desired elment you will see the corresponding XPATH. This takes some practice to get it right. Remeber that we want to find the table corresponding to the “10 Most Populous Countries.” So we activate the xPath finder plugin and the highlight the element of interest. In reality there are a number of ways to find the XML Path or CSS Path for an element within a web page but this is a good one to start. It requires us to install some helper plugins such as the xPath Finder for Firefox and Chrome. Is there a more direct way to find the content ? There is. Well we pulled out all tables and then, by experimentation, we isolated table 6 and got the content corresponding to that. Import net.sf. Italian Giada De Laurentiis 2005 30.00 Harry Potter J K.
