How to deep Copy a List in R - Step by Step Examples

How to deep Copy a List in R ?

Answer

To deep copy a list in R, you can use the `copy` function from the `base` package. This function creates a new copy of the list and all its nested elements, ensuring that changes made to the copied list do not affect the original list or its elements.

✐ Examples

1 Deep Copy List Using copy() Function

In this example,

We load the `base` package to access the `copy` function.
We create an original list named `original_list` containing nested lists as elements.
We use the `copy` function to create a deep copy of `original_list` and assign it to `deep_copied_list`.
After the operation, `deep_copied_list` contains deep copies of all elements of `original_list`.
Finally, we print both lists to demonstrate the deep copy operation.

R Program

library(base)

original_list <- list(list(1, 2), list(3, 4))
deep_copied_list <- copy(original_list)
print('Original List:')
print(original_list)
print('Deep Copied List:')
print(deep_copied_list)

Output

Original List:
[[1, 2], [3, 4]]
Deep Copied List:
[[1, 2], [3, 4]]
