Hi, I'm trying to create a vector (or matrix row) with a specific ordering. For example, I have the following vector: x<-c(0.1,0.2,0.3,0.4,0.5,0.6) that has order order(x) [1] 1 2 3 4 5 6 I want another vector that has the same values as x, but with a different ordering. For example, I want y to have values 0.1, 0.2, etc. but in the order 1-2-5-6-3-4. The answer would be y [1] 0.1 0.2 0.5 0.6 0.3 0.4 Any help would be greatly appreciated. Thanks. -- View this message in context: http://r.789695.n4.nabble.com/Specifying-the-ordering-of-a-vector-tp4542766p4542766.html Sent from the R help mailing list archive at Nabble.com.

Thanks.x[c(1,2,5,6,3,4)] will do it. Duncan Murdoch
