I believe that the line j <- (4,5) is missing a 'c'. As written the answer should be Error: unexpected ',' in "j <- (4,". Good question though. Thank you Steve.

Thanks, good catch. You are correct.
this is fixed.

In addition to the missing 'c' on second vector, error will be thrown on matrix multiplication due to second vector being 1 element shorter than the first. Add 1 to end of second vector. Result 4 10 3.

Not an error. A warning. This still works:
> i <- c(1,2,3)
> j <- c(4,5)
> k <- i * j
Warning message:
In i * j : longer object length is not a multiple of shorter object length
> k
[1] 4 10 12

i <- c(1,2,3)
> j <- c(4,5)
> k <- i * j

I stand corrected, my apologies.
Saw the warning: (my brain registered Error), and did not display the k value.
