Create order of numbers based on a given vector
I don't have access to R so I can't test my example but I think this will work. vec ( as defined by you) # flip the false and the trues vec1<-ifelse(vec==FALSE,TRUE,FALSE) ans<-cumsum(vec) Regards, Ashim

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.
