try this:
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))
vals <- unlist(df1[5, ])
df1[order(vals, decreasing = TRUE)]
I hope it helps.
Best,
Dimitris

Quoting Daniel Wagner <[EMAIL PROTECTED]>:
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))Â Â
df1
  v1 v2 v3 v4
1Â 2Â 8Â 7Â 1
2Â 3Â 5Â 8Â 4
3Â 1 12Â 2Â 6
4Â 9Â 4Â 6Â 3
5Â 5 11Â 9Â 6
I wanto to get the order of df1 on the basis of value in last row
(descending order) like
   v2 v3 v4 v1
1Â 8Â 7Â 1Â 2
2Â 5Â 8Â 4Â 3
3 12Â 2Â 6Â 1
4Â 4Â 6Â 3Â 9
5 11Â 9Â 6Â 5
 Could somebody help me?
