[R] Vector indices

  I am despairing of getting the indices for a vector:   First, I have a table from which I kick out a number of rows with na.omit. Next, I use this table for clustering with kmeans and cl$cluster contains my clusters. The cl$cluster is a vector which still contains my original indices from the very beginning, a kind of like an "associative" array. But how can I get a list of only these indices? When I use which() on the data it returns new indices starting from 1 to N together with the "old" indices but the "old" ones remain unaccessible.   

  It would be great if someone could give me a hand with that.
