This interactive R course covers everything from the basics, variables, and data types to advanced topics, such as recursion, file handling, and S3/S4 classes in R.

In today’s data-driven world, the ability to analyze large datasets is becoming a vital skill across industries. R, one of the most powerful languages for data analysis.
This interactive R course is designed for beginners, with no prior knowledge of R programming required. You will begin with fundamental concepts, such as R variables, data types in R, and basic functions like R print and R cat. As you progress, you will dive into more complex topics, including R vectors, lists, arrays, matrices, and data frames in R programming. You’ll also learn how to perform operations using arithmetic operators in R, relational operators in R, and logical operators in R. Further, the course covers advanced features like if statements in R, switch statements in R, loops in R, and recursion in R. 
Finally, you’ll gain hands-on experience with file handling in R, exception handling with try and except in R, and object-oriented programming using S3 and S4 classes in R.

```r
while (condition) 
{
  ## statements
}
```

```r
do (condition) 
{
  ## statements
} while()
```

```r
while (condition) else
{
  ## statements
}
```

Which of the following syntax is correct for `while` loop?


Which of the following syntax is correct for <code>while</code> loop?

`for` loop will execute a fixed number of times.

`break` will execute a loop while a condition is true

`if...else` tests a condition and lets the compiler execute some statements accordingly

Choose the statement that is false:

______ is used to break the execution of a loop.

______ is used to break the execution of a loop.

The following code will generate a sequence of integers from 1 to 10 :
```r
for (i in 0:9) {
    print(i)
}
```


The following code will generate a sequence of integers from 1 to 10 :
<pre><code class="language-r">for (i in 0:9) {
 print(i)
}
</code></pre>

Which of the following statement can be used to explicitly control looping?

Which of the following statement can be used to explicitly control looping?

______ by default initiates an infinite loop from the start.

______ by default initiates an infinite loop from the start.

The syntax of the `repeat` loop is:
```r
repeat 
{
	break
}
```

The syntax of the <code>repeat</code> loop is:
<pre><code class="language-r">repeat 
{
	break
}
</code></pre>

The syntax of the `for` loop is:
```r
for loop(v in vector)
{
	statement
}
```

The syntax of the <code>for</code> loop is:
<pre><code class="language-r">for loop(v in vector)
{
	statement
}
</code></pre>

We cannot use the `break` statement in a `for` loop.

We cannot use the <code>break</code> statement in a <code>for</code> loop.

In R language, nested `for` loops are allowed.

In R language, nested <code>for</code> loops are allowed.
