R language plays a major role in big data analysis. It is an open source programming language which mainly deals with statistical investigation of data.
R can be self- learnt easily with the help of some online courses or books.
After installing R and R studio, I would suggest to go with some books to kick start. Then read online, take some courses as in udemy and read more and more books. And keep practicing in the R studio. Even if you are without any prior programming experiences, this language is easily understandable and well structured.
Online courses are really worth as it gives you a one to one connection with the instructor while practicing. If you are serious of learning R, don’t be hesitated to take even paid courses.
R’s creators: Ross Ihaka and Robert Gentleman (Stable beta version in 2000)
