Explore the basics of the R language, such as variables, operators, loops, and functions, and solve a few challenges.

Become an R Developer

This module will get us up to speed on R programming and assumes no prior knowledge of the language. We’ll start with the basics of R, such as variables, data types, operators, etc., and work our way up to advanced concepts like functions, classes, and exception handling. We’ll also go through some challenges to enhance our hands-on experience. By the time we’re done, we’ll be able to write detailed, useful code in R.

# Syntax of a `for` loop
The syntax for `for` loop in R language:

```
for(value in vector)
{
  statements
}
```
Let's begin with printing every value in a vector:


myVector <- c(1, 2+2i, "3", 4, 5+5i, "6")

for (v in myVector)
{
  print(v)
}


In the above code, the statement `print(v)` is executed for every element $v$ in the vector `myVector`.

A `for` loop is used to apply the same **statements** or **function calls** to a collection of objects. 

Let's visualize the code flow of `for` loop:

In this lesson, we will learn another type of loop: the for loop.
