# R-Programming Tutorial

# R-Programming for Business Students

## What is R?

R is a free and open-source statistical analysis tool. It is also a complete programming language. The programming can be very different from functional programming (javascript), as it is geared towards vectors, matrices, and data frames.

HOWEVER, all the functional programming elements exist. And as a **helpful transition** to more R-styled programming, I present this functional programming tutorial in R.

Keep in mind, however, that many things that require loops in a functional programming language, can be done in one line in Rāsince R has operators for vectors and matrices. Again, these tutorials are just what I call transition knowledge.
