In this program, You will learn how to find the largest of three numbers using nested if statement in R.

```
Find Greatest among three Numbers
Numbers Is :10 20 40 => 40
Numbers Is :30 20 10 => 30
```

## Example: How to find the largest of three numbers using nested if in R

```
{
x <- as.integer(readline(prompt = "Enter first number :"))
y <- as.integer(readline(prompt = "Enter second number :"))
z <- as.integer(readline(prompt = "Enter third number :"))
if (x > y) {
if (x > z)
print(paste("Greatest is :", x))
else
print(paste("Greatest is :", z))
} else {
if (y > z)
print(paste("Greatest is :", y))
else{
print(paste("Greatest is :", z))
}
}
}
```

#### Output:

```
Enter first number :3
Enter second number :2
Enter third number :55
