5 Objetivo – fundamentos de R
El objetivo principal del taller es que los participantes conozcan y practiquen los conceptos básicos de programación en R. Este conocimiento básico es necesario para que cada participante pueda continuar aprendiendo las herramientas específicas que les son de interés.

6 Contenidos Día 1 1. Introducción 2. Funciones y argumentos 3. Objetos
4. Abrir y guardar archivos Día 2 5. Generación de datos 6. Operadores 7. Manipulación de objetos – indexación Día 3 8. Gráficos 9. Control de flujo

7 Objetivo – fundamentos de R
Dos cosas que este taller NO es: 1. Este taller no puede crear expertos en R en 3 días. 2. Este taller no es sobre estadística u otras aplicaciones particulares de R. Tres cosas que este taller SI es: 1. Este taller es una introducción al lenguaje de R. 2. Este taller se enfoca en aprender sobre programación. 3. Este taller es intenso.

8 ¿Qué es R? R es un lenguaje y ambiente de programación para análisis estadísticos y gráficos. Lenguaje de programación porque esta diseñado para expresar (comunicar) procesos que pueden ser llevados a cabo por computadoras. Ambiente porque es un sistema planeado y coherente de herramientas. R is a statistical computing environment for statistical computation and graphics, and it is a computer language designed for typical and possibly very specialized statistical and graphical applications. The software is available for unix/linux, Windows, and Macintosh platforms under general public license, and the program is available to download from Thousands of contributed packages are also available as well as utilities for easy installation.
