It has been fourteen years since the first edition of R Graphics was published (Murrell 2006) and eight since the second one was released (Murrell 2012). For readers, like me, who read the first edition of R Graphics but skipped the second one, this third edition of R Graphics represents a new, fresh updated version of the book. In transit from the first to the third edition, in addition to including new material, Dr. Murrell has introduced key changes and some rearrangements that have made the whole book more understandable, especially the concepts related to viewports and coordinate systems. Although major changes were made in the second edition of the book (Cook and Hofmann 2011), this third edition also introduces some changes. This is evident comparing the indexes of the second and the third editions. In particular, paraphrasing the preface of this third edition, Chapter 8 (devoted to developing new grid graphical functions and objects) has been completely rewritten and the fourth part of the book extensively restructured (and, I would add, reduced).
