  • In an experiment study, various treatments are applied to test subjects and the response data is gathered for analysis. A critical tool for carrying out the analysis is the Analysis of Variance (ANOVA).

  • R is a system for statistical computation and graphics. It provides, among other things, a programming language, high level graphics, interfaces to other languages and debugging facilities.
  • The R language is a dialect of S which was designed in the 1980s
  • Its principal designer,

  • was awarded the 1998 ACM Software Systems Award for S.
  • The language syntax has a superficial similarity with C, but the semantics are
  • variety with stronger affinities with Lisp and APL.
  • It is possible to get quite far using R interactively, executing simple expressions from the command line.
  • Some users may never need to go beyond that level
  • The design of the language contains a number of fine points and common pitfalls which may surprise the user.
  • In some cases, there are multiple ways of performing a task, but some of the techniques will rely on the language implementation, and others work at a higher level of abstraction. In such cases we shall indicate the preferred usage.
  • R does not provide direct access to the computer's memory but rather provides a number of specialized data structures we will refer to as objects.
  • In R, however, the symbols are themselves objects and can be manipulated in the same way as any other object. This is different from many other languages and has wide ranging effects.
  • This is an introduction to the R language, explaining evaluation, parsing, object oriented programming, computing on the language, and so forth.

      En esta pagina se entiende el lenguaje R como un dialecto de S. Este lenguaje R sirve tanto para programacion, como para crear graficas de alto nivel de dificultad... Tambien nos da una breve explicacion sobre algunos de los comandos usados para R tanto como parte de la gramatica del lenguaje mismo.

      He aquí otra página que aparte de darnos una introducción del legunaje R, nos enseña paso a paso sus símbolos y de cómo escribir y programar en dicho lenguaje. Otra anotación a tener en cuenta es que nos vuelve a repetir que es de muy fácil aprendizaje y de las ventajas de las que dispone
  • The language is actually fairly simple, but it is unconventional. These notes are intended to make the language easier to learn for someone used to more commonly used languages such as C++, Java, Perl, etc.
  • R is more than a programming language. It is an interactive environment for doing statistics

      Creo que lo marcado dice mucho sobre el lenguaje. Simplemente nos dice que dicho lenguaje es muy fácil de comprender y de que una vez dominado el programador será capaz de organizar y gestionar grandes cantidades de datos.
