R () is an extensive statistical natural environment and programming language for Specialist information Investigation and graphical Show.
Though used mainly by statisticians and various practitioners necessitating an surroundings for statistical computation and computer software development, R also can run for a general matrix calculation toolbox – with overall performance benchmarks akin to GNU Octave or MATLAB. Arrays are stored in column-key order. Offers
