Subject: [R] which.minimums not which.min
Hi
Is there a function which determines the location, i.e., index of the all
minimums or maximums of a numeric vector.
Which.min(x) only finds the (first) of such.
> x <- c(1:4,0:5, 4, 11)
> x
[1] 1 2 3 4 0 1 2 3 4 5 4 11
> which.min(x)
[1] 5
> which.max(x)
[1] 11
>
but I need
which.min(x) to be 5 11
which.max(x) to be 4 10
thanks
