R provides a wide range of functions for obtaining summary statistics. One method of obtaining descriptive statistics is to use the sapply( ) function with a specified summary statistic. Possible functions used in sapply include mean, sd, var, min, max, median, range, and quantile.

R is distributed with fifteen "base packages": base, compiler, datasets, grDevices, graphics, grid, methods, parallel, splines, stats, stats4, tcltk, tools, translations, and utils.

The important functions of statistics are: Statistics helps in gathering information about the appropriate quantitative data. It depicts the complex data in graphical form, tabular form and in diagrammatic representation to understand it easily. It provides the exact description and a better understanding.

R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues.

Base packages contain the basic functions that allow R to work, and enable standard statistical and graphical functions on datasets; for example, all of the functions that we have been using so far in our examples. The directories in R where the packages are stored are called the libraries.
