Create order of numbers based on a given vector
I think you can use the cumsum function. If you think of your falses to 1 and your trues to 0 then you're just sequentially adding the numbers in the vector. x = c(FALSE, FALSE, TRUE, FALSE, TRUE, TRUE, FALSE, FALSE) y = rep(1,length(x))*(1-x) cumsum(y) Hope that helps, Sam

Hello! If I have a vector vec <- c(FALSE, FALSE, TRUE, FALSE, TRUE, TRUE, FALSE FALSE) I can I create the following order of numbers based on vector vec: 1, 2, 2, 3, 3, 3, 4, 5 Whenever there is a FALSE I increase the number (starting with 1). Whenever there is a TRUE I set the same number as the previous FALSE has been assigned to. I would be happy for any input Cheers, Syrvn -- View this message in context: http://r.789695.n4.nabble.com/Create-order-of-numbers-based-on-a-given-vector-tp3901158p3901158.html Sent from the R help mailing list archive at Nabble.com.
