generate sequences for every element of a vector
Untested, wouldn't outer(x, 0:n,"+") work as well and be a little faster? M

One option is: x <- c(3, 8, 14, 24, 34, 40) c(sapply(x, seq, length = 3)) I hope it helps. Best, Dimitris On 10/7/2011 3:40 PM, Martin Batholdy wrote:
Dear R-List, I have the following problem: I have a vector that looks like this: x<- c(3, 8, 14, 24, 34, 40) And I would like to make a sequence out of every element, starting at the value of this element. So that I get a vector just like this: x<- c(3, 4, 5, 8, 9, 10, 14, 15, 16, 24, 25, 26, 34, 35, 36, 40, 41, 42) How can I do this without looping over the whole vector or something like this? thanks for any suggestions!
