Data Analysis Using R Programming

Abstract

Beginning RR is an open-source, freely available, integrated software environment for data manipulation, computation, analysis, and graphical display. The R environment consists of *a data handling and storage facility, *operators for computations on arrays and matrices, *a collection of tools for data analysis *graphical capabilities for analysis and display, and *an efficient, and continuing developing programming algebra-like programming language which consists of loops, conditionals, user-defined functions, and input and output capabilities. Many R programs are available for biostatistical analysis in Genetic Epidemiology. Typical examples are shown.
