Word Clouds
Today Stephanie Labou spoke about text mining and word clouds. Our script today used the “tm” and “wordcloud” packages.
Some questions were asked at our session, primarily 1) can you mine PDFs? The answer is yes! You can! You can find more information about reading in text from PDFs here and here and here is the online book about text mining in R (including sentiment analysis and n-grams).
Here is some example text to run with the script: data_skills_ms , sourced from Stephanie Labou’s paper
