I can't see anything on the reference given that indicates that the correct answer is the correct answer. The examples given on there all suggest that none of the answers provided are right.

On two occasions I have been asked, "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

Answers 2 and 4 are both correct. Answer 4 is more accurate in terms of what the documentation says (help("seq")) but here is "incorrect". Oh well.

I think it has to be 'by =' not just 'by'.

I think the possible answers have been edited because when I looked it was "by = 2"

I just guessed not even knowing what language this was about. The QOTD in my email has no subject.

I was assuming the "=" missing was a typo (which is so common here).

While I haven't actually worked with R, from the questions I've seen here, it looks like a remarkably intuitive language. Those of you who have experience with R, is that really the case?

That works, but no = in the answer choices
