4. Important features of R
 R is a well-developed, simple and effective programming
language which includes conditionals, loops, user defined
recursive functions and input and output facilities.
 R has an effective data handling and storage facility,
 R provides a suite of operators for calculations on arrays,
lists, vectors and matrices.
 R provides a large, coherent and integrated collection of
tools for data analysis.
 R provides graphical facilities for data analysis and
display either directly at the computer or printing at the
papers.
