Practical Data Science with R update

Just got the following note from a new reader:

Thank you for writing Practical Data Science with R . It’s challenging for me, but I am learning a lot by following your steps and entering the commands.

Wow, this is exactly what Nina Zumel and I hoped for. We wish we could make everything easy, but an appropriate amount of challenge is required for significant learning and accomplishment.

Of course we try to avoid inessential problems. All of the code examples from the book can be found here (and all the data sets here ).

The second edition is coming out very soon. Please check it out .
