Hello, I have a vector with positive integer numbers, e.g.
> numbers <- c(1,2,1,2,3,4,5) and want to split the vector whenever an element in the vector is smaller or equal to its predecessor. Hence I want to obtain two vectors: c(1,2) and c(1,2,3,4,5). I tried with which(), but it is not so elegant: > numbers[1:(which(numbers<=numbers[1])[2]-1)] > numbers[which(numbers<=numbers[1])[2]:length(numbers)] Sure I can do it with a for-loop, but that seems a bit tedious for that small problem. Does maybe anyone know a simple and elegant solution for this? I'm searching for a general solution, since my vector may change and maybe be split into more than two vectors, e.g. give five vectors for c(1,1,2,3,4,5,1,2,3,2,3,4,5,6,4,5). Many thanks in advance, Hannes -- View this message in context: http://r.789695.n4.nabble.com/splitting-a-vector-tp4638675.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
