| which.min {base} | R Documentation |
Determines the location, i.e., index of the (first) minimum or maximum of a numeric vector.
which.min(x) which.max(x)
x |
numeric vector, whose min or max
is searched (NAs are allowed). |
an integer of length 1 or 0 (iff x has no
non-NAs) , giving the index of the first minimum or
maximum respectively of x.
If this extremum is unique (or empty), the result is the same (but more
efficient) as which(x == min(x)) or which(x == max(x))
respectively.

which.is.max in package nnet differs in
breaking ties at random (and having a “fuzz” in the definition
of ties).
x <- c(1:4,0:5,11) which.min(x) which.max(x) ## it *does* work with NA's present: presidents[1:30] range(presidents, na.rm = TRUE) which.min(presidents)# 28 which.max(presidents)# 2
