Extra Topics in R (with cool examples!!!)
Here are the R script examples we discussed in class.
wordCloudR.r – This creates a colorful word cloud based on a text input file (for the example: 2502.txt).
MySQL-Example.r – This queries the moviedb schema on our class server. It will work with any MySQL account.
aRules(MySQL).r – This queries the bank table I built in my own schema (m0ws.bank). If you want to use your own schema you’ll have to build the table using a SQL script that I can provide upon request.
And here is the brief slide deck on the topic.

Don’t forget to complete the online course evaluation for this class!
You can access the ESFF site here. The deadline is May 3 (well, technically May 4 at 8:00 AM, but are you really going to get up early on May 4 to do it?).
It only will take you five minutes, but it is important.
Some things about the course evaluations:
- Your feedback is anonymous.
- I don’t get the results until after the semester is completely over.
- I really look at the feedback and use it to make changes for future semesters.
