It seems that more often, the x-axis is recall and the y-axis is precision.

Thanks! I agree that should be changed in the book. I'm actually surprised I did it this way around.
The one benefit is then you have recall on the y axis in both the PR curve and ROC curve but indeed that's not the standard convention.
