Suppose you're working on a task in R that involves performing operations on all pairs of elements from two vectors. How would you approach this without using nested loops?

  • Use the expand.grid() function to generate combinations and apply a function to each pair
  • Use the for loop with indexing to iterate over each pair of elements
  • Use the lapply() function with the combn() function to generate combinations and apply a function to each pair
  • Use the mapply() function to iterate over each pair of elements
To perform operations on all pairs of elements from two vectors without using nested loops, you can use the expand.grid() function to generate combinations of the elements from both vectors. Then, you can apply a function to each pair of elements using apply() or related functions.
