How to Create a For Loop with Range in R?

In this article, we will discuss how to create a for loop with range in R Programming Language.

For loop is used to iterate the elements over the given range. We can use for loop to append, print, or perform some operation on the given range of integers. Consider the below syntax of the for loop that also contains some range in it.

Syntax:

for(iterator in range) {
    # statements
}

where,

• range is the range of values that contains start:stop
• iterator is  available used to iterate the elements over the given range

Example 1: Print values in a range

R

# create a range with 1 to 5 numbers
for(i in 1: 5) {

    # display the values
    print(i)
}

Output:

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5

Example 2: Perform Operation on Values in Range

We can also perform some mathematical operations over the range of values inside for loop.

Syntax:

for(iterator in range) {
//operations
}

where,

• range is the range of values that contains start:stop
• iterator is  available used to iterate the elements over the given range
• operations is used to perform some mathematical operations

R

# create a range with 1 to 5 numbers
for(i in 1: 5) {

    # display the values by performing
    # square of numbers
    print(i*i)
}

Output:

[1] 1
[1] 4
[1] 9
[1] 16
[1] 25

Example 3: Performing operations on values in a vector

Here we are going to append the values to the vector by using for loop.

Syntax:

for(iterator in range) {
  vector=c(vector,iterator )
}

Example:

R

# create a vector
vector1 = c(2, 3)

# create a range with 1 to 5 numbers
for(i in 1: 5) {

    # append values to a vector
    vector1 = c(vector1, i)
}

# display
vector1

Output:

[1] 2 3 1 2 3 4 5
