Can you describe a scenario where you would need to use nested loops in R?
- Processing multi-dimensional data structures
- Simulating complex systems
- Generating all combinations of elements
- All of the above
One scenario where you would need to use nested loops in R is when you need to generate all combinations of elements from multiple vectors or iterate over multi-dimensional data structures such as arrays or matrices. Nested loops provide a way to systematically traverse and process these structures or combinations.
