Learn how to manipulate functions and expressions to modify how the R language interprets itself. This book is an introduction to metaprogramming in the R language, so you will write programs to manipulate other programs. Metaprogramming in R shows you how to treat code as data that you can generate, analyze, or modify. R is a very high-level language where all operations are functions and all functions are data that can be manipulated. This book shows you how to leverage R's natural flexibility in how function calls and expressions are evaluated, to create small domain-specific languages to extend R within the R language itself. What You'll Learn Find out about the anatomy of a function in R Look inside a function call Work with R expressions and environments Manipulate expressions in R Use substitutions Who This Book Is For Those with at least some experience with R and certainly for those with experience in other programming languages.

Informatics Education - Supporting Computational Thinking by Roland Mittermeir,Maciej M. Syslo Pdf

Informatics Education – Supporting Computational Thinking contains papers presented at the Third International Conference on Informatics in Secondary Schools – Evolution and Perspective, ISSEP 2008, held in July 2008 in Torun, Poland. As with the proceedings of the two previous ISSEP conferences (2005 in Klag- furt, Austria, and 2006 in Vilnius, Lithuania), the papers presented in this volume address issues of informatics education transcending national boundaries and, the- fore, transcending differences in the various national legislation and organization of the educational system. Observing these issues, one might notice a trend. The p- ceedings of the First ISSEP were termed From Computer Literacy to Informatics F- damentals [1]. There, broad room was given to general education in ICT. The ECDL, the European Computer Driving License, propagated since the late 1990s, had pe- trated school at this time already on a broad scale and teachers, parents, as well as pupils were rather happy with this situation. Teachers had material that had a clear scope, was relatively easy to teach, and especially easy to examine. Parents had the assurance that their children learn “modern and relevant stuff,” and for kids the c- puter was sufficiently modern so that anything that had to do with computers was c- sidered to be attractive. Moreover, the difficulties of programming marking the early days of informatics education in school seemed no longer relevant. Some colleagues had a more distant vision though.

Object-Oriented Programming in R by Thomas Mailund Pdf

Object-oriented programming is a powerful paradigm for constructing reusable and maintainable code. This book gives an introduction to object-oriented programming in the R programming language. Object-oriented programming is a style of programming that focuses on data as "objects" that have state and can be manipulated by polymorphic or generic methods.In object-oriented programming, you model your programs by describing which states an object can be in and how methods will reveal or modify that state. Object-oriented programming achieves high flexibility through so-called polymorphism, where which concrete methods are executed depends on the type of data being manipulated.In this book, I teach you how to write object-oriented programs. How to construct classes and class hierarchies in the three object-oriented systems available in the R programming language, and how to exploit polymorphism to write flexible and extendable software.
