How to Iterate Over a Vector in R - Step by Step Examples

How to Iterate Over a Vector in R ?

To iterate over a vector in R, you can use a for loop to access each element of the vector one by one.

In this example,

First, we create a numeric vector named vec with a series of numeric values.
We then use a for loop to iterate over each element of the vector. The loop variable item will take on the value of each element in the vector, one at a time.
Inside the loop, we use the print function to print the current value of the loop variable item.
The print function sends the value of item to the console, allowing us to see each element of the vector as it is processed.

vec <- c(10, 20, 30, 40, 50)
for (item in vec) {
    print(item)
}

[1] 10
[1] 20
[1] 30
[1] 40
[1] 50

In this example,

First, we create a character vector named char_vec with a series of string values.
We then use a for loop to iterate over each element of the vector. The loop variable item will take on the value of each element in the vector, one at a time.
Inside the loop, we use the print function to print the current value of the loop variable item.
The print function sends the value of item to the console, allowing us to see each element of the vector as it is processed.

char_vec <- c("apple", "banana", "cherry", "date", "elderberry")
for (item in char_vec) {
    print(item)
}

[1] "apple"
[1] "banana"
[1] "cherry"
[1] "date"
[1] "elderberry"
