Analyze Google+ Posts with R [Update]

Analyze google+ posts with R

Hey everybody,

today I show you how you can start working with the Google+ API to analyze Google+ posts with R. We create a personal API key, get our own stats and plot them in a nice looking graph.

Get the API Key

You can get our API key on the Google Developer console here: https://code.google.com/apis/console

There you can see an overview of you API activities if you have some. To create a new API connection click on “APIs” and turn on the Google+ API.

After you did this, you can click on “Google+” and you see a list of the available API calls. Now click on “Credentials” on the left and click on “Create new key” to create a new public API access. Then click on “Browser key” and then “Create”.

And there it is: you API key.

Analyze Google+ Posts with R

For our first analysis we need the packages

 

 

And we need our api key and our user id:

 

 

In this case I used my own Google+ ID but you can use every ID you want. But we can just receive the public posts.

We get our raw data and put it in a JSON object with:

 

 

We can now put the data in a DataFrame to make it more readable. But we don´t need all the values we received as these are a lot. We get the fields

df

 

We can save this DataFrame as a CSV file with:

 

Visualize your Posts

To visualize your posts we extract the informations we need and store them in the Data Frame df_graph

Then we can plot it with

During my time at university and learning about the basics of economics I started heavily exploring the possibilities and changes caused by digital disruptions and the process of digital transformation, whereby I focused on the importance of data and data analytics and combination with marketing and management.
My personal focus of interest lies heavily on technology, digital marketing and data analytics. I made early acquaintance with programming and digital technology and never stop being interested in following the newest innovations.

I am an open, communicative and curious person. I enjoy writing, blogging and speaking about technology.

  • So, why would we want to do this? What does R bring to scatterplots of Google+ accesses?

    • Hey hypergeometric,
      thanks for your comment.
      My purpose of this post was on the one hand to show again the possibilities of R as something more than “just” a statistical language. With all its packages R got a lot of more different layers.
      And on the other hand to show some of the possibilities of the Google+ API, which is not as developed as the Facebook API but also has some cool functions.
      And to bring these two aspects together I wrote this post.
      And you should do this when you are interested in your posts performance on Google+. This is more about Social Monitoring than about statistical computing.
      I hope I could help you.
      Regards

  • Cool. 🙂

    Hi, it is really good, thanks for sharing!

    Also, I’d like to know if is possible to do something like they did for twitter using TwitterR (https://sites.google.com/site/miningtwitter/mining-viz).

    Best,
    Demetrius.

    • Hey Demas,
      there are a lot of possibilites of working with Google+. This is a very interesting topic and I will write some new tutorials when I have some time. So follow my blog and you get noticed when there are new tutorials available.
