R help - Jul 2007 - row index

Dear Friends,

Suppose I have a vector as follows

RI  Value

1     10
2     11
3      8
4      4
6     12

I would like a function which returns the"row index number" for the
minimum value of VALUE. Can somebody please give me some direction on how I can
do this. In effect I'm trying to find a comparable function for the GAUSS
command "minindc"
>From the GAUSS Manual
minindc: 
Returns the row number of the smallest element in each column of a matrix


Thanks in advance

Anup
