Ris 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. r can be considered as a different implementation of s. there are some important differences, but much code written for s runs unaltered under r. why are statistical programming languages important to data scientists? what are some advantages and disadvantages the r programming language has over the other main statistical programming languages (i. e. python, sas, sql)?
