What is R? • R is a statistical computing environment • Effective data handling and storage of outputs is possible • Free software • Available for Windows, Unix, Linux and Macintosh platforms • R is an interpreter • R is a case-sensitive language 30 -09 -2020 BMSIT&M, MCA, SAMSHODHANA SAMVAADA 3

R Environment R is an integrated suite of software facilities for data manipulation, calculation and graphical display. It includes • an effective data handling and storage facility, • a suite of operators for calculations on arrays, in particular matrices, • a large, coherent, integrated collection of intermediate tools for data analysis • graphical facilities for data analysis and display either on-screen or on hardcopy, and • a well-developed, simple and effective programming language which includes conditionals, loops, user-defined recursive functions and input and output facilities. 30 -09 -2020 BMSIT&M, MCA, SAMSHODHANA SAMVAADA 4
