R- Programming

R is an open source programming language and software environment for statistical computing and graphics that is supported by the R Foundation for Statistical Computing. The R language is widely used among statisticians and data miners for developing statistical software and data analysis.Polls, surveys of data miners, and studies of scholarly literature databases show that R's popularity has increased substantially in recent years

COURSE OUTLINE
