• 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

How so?

No editing has taken place today

• Fair enough, my mistake 🙂
