Is there a way I can obtain some of the sample data sources used in the book for examples?
ch01/ data/web_traffic.tsv , is that file available somewhere?
To answer my own question, I bought the book through www.packtpub.com. On my the account page, found the resources for every book I bought.
I got the source codes for all chapters and associated data set with them from the website. They mail it to you, if you request there.
