I am converting some matlab code into R that use inverse of the complementary error function, erfcinv and did not find an equivalent in R, is there such a function in some contributed modules?
Basically, it is qnorm() with suitable scaling. The help page for Normal has the construction for erfc() from pnorm() so just solve erfc(x) = y for x.
