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]] 0,0,0,0,0 [[3]] 1,1,1,1,1,1 catching every group of contiguous repeated values.
