Imagine you need to create a 3x3 matrix in R containing the numbers 1 to 9. How would you do this?

  • matrix(1:9, nrow = 3, ncol = 3)
  • matrix(1:9, nrow = 3)
  • matrix(c(1, 2, 3, 4, 5, 6, 7, 8, 9), nrow = 3, ncol = 3)
  • matrix(c(1, 2, 3, 4, 5, 6, 7, 8, 9), nrow = 3)
To create a 3x3 matrix in R containing the numbers 1 to 9, you can use the matrix() function and pass the sequence 1:9 as the values argument. You also need to specify the number of rows (nrow = 3) and the number of columns (ncol = 3) to create the desired matrix dimensions.
