Summary
Welcome to the world of statistical programming. This book will contain a lot of specific advice about the hows and whys of the subject. We start in this chapter by giving you an idea of what statistical programming is all about. We will also tell you what to expect as you proceed through the rest of the book. The chapter will finish with some instructions about how to download and install R, the software package and language on which we base our programming examples.
What is statistical programming?
Computer programming involves controlling computers, telling them what calculations to do, what to display, etc. Statistical programming is harder to define. One definition might be that it's the kind of computer programming statisticians do – but statisticians do all sorts of programming. Another would be that it's the kind of programming one does when one is doing statistics – but again, statistics involves a wide variety of computing tasks.
For example, statisticians are concerned with collecting and analyzing data, and some statisticians would be involved in setting up connections between computers and laboratory instruments – but we would not call that statistical programming. Statisticians often oversee data entry from questionnaires, and may set up programs to aid in detecting data entry errors. That is statistical programming, but it is quite specialized, and beyond the scope of this book.
