How to Iterate Over a List in R - Step by Step Examples
How to Iterate Over a List in R ?
Answer
To iterate over a list in R, you can use a for loop or apply functions like lapply or sapply.
✐ Examples
1 Iterate Over List using For Loop
In this example,
- We create a list named
numbers
with numeric elements. - We use a for loop to iterate over each element in the list.
- Within the loop, we print each element to the console.
R Program
numbers <- c(10, 20, 30, 40, 50)
for (num in numbers) {
print(num)
}
Output
10 20 30 40 50
2 Iterate Over List using lapply Function
In this example,
- We create a list named
numbers
with numeric elements. - We use the
lapply
function to apply a function (e.g., print) to each element in the list. - The result is printed to the console.
R Program
numbers <- c(10, 20, 30, 40, 50)
lapply(numbers, print)
Output
[1] 10 [1] 20 [1] 30 [1] 40 [1] 50
