Читать книгу The Big R-Book - Philippe J. S. De Brouwer - Страница 231

Secondly, it is of great importance that it is possible to use R without even knowing that the OO system exists. In fact, for most of the following chapters in this book, it is enough to know that the generic-function implementation of the OO logic exists.
