Suppose you're asked to write a function in R that takes an array of numbers and returns a new array with each element squared. How would you do it?
- Use a nested for loop to iterate over each element and calculate the square
- Use the apply() function with a custom function to calculate the square of each element
- Use the ^ operator to raise the array to the power of 2
- Use the sqrt() function to calculate the square root of each element
To write a function in R that takes an array of numbers and returns a new array with each element squared, you can use a nested for loop to iterate over each element of the array and calculate the square. By storing the squared values in a new array, you can return the resulting array as the output of the function.
