why was there a need of programming language 'R' ?

Question

Can c or python replace R?

Answer 1

Well, it's true that R is not exactly necessary... in the same way that calculators aren't necessary. You could replace a calculator with a pencil and a piece of paper, and you'd still get the same functionality, right?

Point is, we still have R because it makes mathematical functions, plotting, matrix operations, etc. a lot easier. Convenience is key - it's the reason we even have high-level programming languages to begin with. Then again, you could try writing your own mathematical functions in C for the same purpose, after all. R's just there to make it easier on us.

Answer 2

Because some people thought there's a need for a new language (for statistics, data structures...)
