Renumbering rows after ordering in R programme

Question

I have ordered a set of rows to get this:

2   1983  TRI-COUNTY  TRAUTH         0.1495 0.1395     NA      452 0.0764      4      0  06/02/83
4   1983  TRI-COUNTY          


        

Answer 1

Another solution, normally used when binding rows:

dataset <- rbind( dataset , make.rows.names=FALSE )
