Introduction To R Language

This document provides an outline of topics for learning the R programming language, including R basics, vectors and factors, arrays, matrices, lists, data frames, if/else statements, for loops, user defined functions, objects and classes, reading data files, string operations, and regular expressions. Key concepts covered are defining vectors and factors, performing operations on vectors, summarizing data, accessing and manipulating arrays and matrices, the structure and operations of data frames, using if/else statements and for/while loops, defining user functions, detecting object classes and converting between types, reading different file types into R, and using string and regular expression functions.
