The R magics have seemed to have changed quite a lot over time in terms of interface. For example, I updated the R code for the first edition of this book a few times. The current version of DataFrame assignment returns pandas objects, which is a major change. Be careful with the version of Jupyter that you use as the %R code can be quite different. If this code does not work and you are using an older version, consult the Notebooks of the first edition of this book, as they might help.
