[R] find the index of the smallest or biggest number in a vetor or data.frame

Dear R experts, How to find out the index of minimum or maxmum number in a vetor or data.frame? For example, a= n price 1 50 -2100 0200 -1 300 .. I want to find out the row which the n is the smallest or largestest and extract the price. Thanks Ted -- View this messag
