R Course

R is a language built specifically for statistics and data analysis, created by statisticians for other statisticians — that focus shows up everywhere, from how naturally it handles a column of numbers to functions like summary() that exist in almost no other general-purpose language.

What you'll learn

You'll start with R's core building blocks — variables, vectors, operators, conditionals, loops, and functions — with a close look at the two things that make R feel different from most other languages: 1-based indexing and vectorized operations, where arithmetic applies to an entire column of numbers at once instead of one value at a time.

The second half moves into what R is actually used for day to day: data frames (R's table structure), the built-in statistics functions like mean(), median(), and summary(), and turning a plain vector into a chart with plot(). Every lesson shows real R code alongside the exact console output it produces, so you can read it closely, then run it yourself in R or RStudio.
