Dear R experts,  I have a dataframe with 4 columns (variables). I want to redorder (or reposition) these columns on the basis of a value in its last row. e.g.  df1<-data.frame( v1= c(2,3,1,9,5), v2=c(8,5,12,4,11), v3=c(7,8,2,6,9), v4=c(1,4,6,3,6))  > df1   v1 v2 v3 v4 1 2 8 7 1 2 3 5 8 4 3 1 12 2 6 4 9 4 6 3 5 5 11 9 6
I wanto to get the order of df1 on the basis of value in last row (descending order) like    v2 v3 v4 v1 1 8 7 1 2 2 5 8 4 3 3 12 2 6 1 4 4 6 3 9 5 11 9 6 5  Could somebody help me?  Daniel Amsterdam     Send instant messages to your online friends http://uk.messenger.yahoo.com [[alternative HTML version deleted]]
