Unfortunately I do not know whether these functions assume unit or one standard deviation shocks. I tried to look into the code of these functions, but in vain: neither irf, nor vars::irf, nor vars:::irf output the code of the functions. Does someone know whether irf and fevd assume one standard deviation or a unit shock? How can I see the code of these functions?

?getAnywhere

should do it
