One advantage of this method is if you want the first 20 elements from repeating a vector of seven items it won't set your hair on fire. :) -- Protege: What is this seething mass of parentheses?!

Re: Repeating a vector n times
Ken, that'll result in the original vector back out again. (vec (take 3 (cycle [1 2 3]))) => [1 2 3].

RE: Repeating a vector n times
Thanks Tamreen. Your solution will have to be wrapped in another vec call. I will use Miekel's: (reduce into [] (repeat n xs)).

Aw: Repeating a vector n times
Hi, you could use (reduce into [] (repeat n xs)). Sincerely Meikel -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Repeating a vector n times
I have to write a function that will take a vector as input, repeat the elements multiple times and return back a single vector of the repeated items. I came up with the following but am wondering if there is a better or simpler way to write this: (def xs ["a" "b" "c"]) (defn repeat-vec-n [xs n] (vec (reduce concat [] (take n (repeat xs) OUTPUT: user=> xs ["a" "b" "c"] user=> (repeat-vec-n xs 3) ["a" "b" "c" "a" "b" "c" "a" "b" "c"] -- Shoeb -- You received this message because you are subscribed to the Google Groups "Clojure" group.
