- | R is an integrated suite of software facilities for data manipulation, | ||
- | 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, | ||
