196_wordcloud_ex6This page illustrates the possibilities offered by the amazing wordcloud2 package developped by Chiffon Lang. It is largely inspired from the well done vignette.

First, let’s get an example dataset  and load the library:


196_wordcloud_ex1

 

 

 

We start with the default wordcloud, without changing any argument. Just adjust the size of the wordcloud with the size argument.

It is possible to change words and background colors.

You can change the shape of the wordcloud. Several shapes are proposed with the package: ‘circle’ (default), ‘cardioid’, ‘diamond’ (alias of square), ‘triangle-forward’, ‘triangle’, ‘pentagon’, and ‘star’).

It is also possible to use any image you have as a mask! Just put the image in the current working directory and use it like in the code below.

Control the rotation of words with 3 arguments: minRotation, maxRotation and rotateRatio.
