Author here. Granted, absolutely. I think you have a great point. I understand this might seem downright neurotic. While I really am into numbers, or rather, finding out how things really work, to me, this has been more about learning R properly and doing so in a context of both novelty and perhaps some degree of relevance. In a way it has been my tinkering hobby to take my thoughts off the wicked problems I deal with at work. But you're absolutely right that this has taken some accumulated amount of effort to build. If I had done this as a consulting project, it would have cost something like two decades worth of clothes. So as a total investment, hardly worth the while. But I would to think that perhaps something good comes out of this way of looking at it. Now I'm in a way done and find that I look for the next thing to fill that new void in my mental real estate.
