💡 Hint

Common Mistakes

Using - instead of + causes subtraction.

In R, the + operator adds vectors element-wise.

Common Mistakes

Using + adds instead of subtracts.

The - operator subtracts vectors element-wise in R.

4fill in blank

hard

Fill both blanks to divide two vectors element-wise and assign to result.

R Programming

result <- c(10, 20, 30) [1] c(2, 4, 5) [2] 2

💡 Hint

Common Mistakes

Using + or - instead of division or multiplication.

The / operator divides vectors element-wise. The * operator multiplies the result by 2.

5fill in blank

hard

Fill all three blanks to create a vector of squared differences between two vectors.

R Programming

result <- (c(3, 6, 9) [1] c(1, 2, 3)) [2] [3]

💡 Hint

Common Mistakes

Using + instead of subtraction.

Using * instead of exponentiation.

Subtract vectors element-wise with -, then raise to the power ^ of 2 to square the differences.
