I’ve always had a love/hate relationship with R but ever since I generated a Word Cloud using RapidMiner and R, I’ve come to like it’s visualization capabilities.

I stumbled across this recently written article by Jonas Schöley over at his blog jschoeley.github.io and found some really need Data Visualizations in R and code examples. The one using Bubble Grid vs Choropleth maps caught my eye. Check it out, it has ready to go R code.

Word Clouds in RapidMiner and R

There was a question from the RapidMiner Community on how to make a word clouds in RapidMiner using R. It’s really easy.

First you’ll need to make sure you have the Execute R extension installed and configured, then you need to download the “wordcloud” and “RColorBrewer” packages from R Cran Repository.

 

Finally, grab this sample XML and pop it in your RapidMiner Studio. Note: I saved the image to my desktop, you’ll have to repath it to where you want to save the PNG.
