How to Access Elements in a List in R - Step by Step Examples

How to Access Elements in a List in R ?

To access elements in a list in R, you can use indexing or iterate over the list using loops.

In this example,

We create a vector named num_vector with numeric elements.
We access elements by their index using square brackets and print them to standard output.

num_vector <- c(1, 2, 3, 4, 5)
element <- num_vector[3]  # Accessing element at index 3
print(paste("Element at index 3:", element))

[1] "Element at index 3: 3"

In this example,

We create a vector named str_vector with string elements.
We iterate over the vector using a for loop and print each element to standard output.

str_vector <- c("Apple", "Banana", "Cherry")
for (item in str_vector) {
  print(item)
}

[1] "Apple"
[1] "Banana"
[1] "Cherry"

In this tutorial, we learned How to Access Elements in a List in R language with well detailed examples.
