Have a look at switch() and which.min()
x <- c(a = 3, b = 1, c = 5)
switch(which.min(x), "a is lowest", "b is lowest", "c
is lowest")

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data.
~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.
