WHAT IS “R” ??
“R is an integrated suite of software facilities for data manipulation, calculation and graphical display.
Among other things it has:
(1) an effective data handling & storage facility,
(2) a suite of operators for calculations on arrays, in particular matrices,
(3) a large, coherent, integrated collection of intermediate tools for data analysis,
(4) graphical facilities for data analysis and display either directly at the computer or on hard-copy, and
(5) a well-developed, simple, and effective programming language (called ‘S’) which includes conditionals, loops, user-defined recursive functions and input and output facilities.”
“R” is case-sensitive & is considered an expression language.
Statistics & R
“R” is often utilized as a statistics system.
“R”, together with various packages provided by the CRAN family, allow “R” to utilize most classical statistics & modern methodologies.
“R” differs from other languages utilized for statistical analysis, in that “R” “will give minimal output and store the results in a fit object for subsequent interrogation by further R functions.”
Languages like SAS & SPSS, will give more output–than “R”–from techniques like regression.
