try this:
v <- rnorm(10)
v
order(v, decreasing = TRUE)[1:2]
I hope it helps.
Best,

Subject: [R] which.max2()
Hello,
which.max() only returns one index value, the one for the
maximum value. If I want the two index values for the two
largest values, is this a decent solution, or is there a
nicer/better R'ish way?
max2 <-function(v)
{
m=which.max(v)
v[m] = -v[m]
m2=which.max(v)
result=c(m, m2)
result
}
Seems to work ok.
Thanks,
Esmail
