Re: [R] split array into groups by value

Rui and Dimitris, thank you much, both approaches work great! (although rle won me, I had a feeling something like that had to exist) -- View this message in context: http://r.789695.n4.nabble.com/split-array-into-groups-by-value-tp4448578p4451048.html Sent from the R help mailing list archive at

Re: [R] split array into groups by value

One approach is: l <- c(1,1,1,1, 0,0,0,0,0, 1,1,1,1,1,1) r <- rle(l)$lengths split(l, rep(seq_along(r), r)) I hope it helps. Best, Dimitris On 3/6/2012 3:53 AM, pavlo wrote: I have an array l<- c(1,1,1,1, 0,0,0,0,0, 1,1,1,1,1,1) I would like to get a rugged array [[1]] 1,1,1,1 [[2]] 0,0,0
