[R] Combining elements of vectors

Dear list, I have a vector of elements which I want to combined each with each, but none with itself. For example, v - c(a, b, c) and I need a function 'combine' such that combine(v) [[1]] [1] a b [[2]] [1] a b [[3]] [1] b c I am not very interested in the orders of the output items for

Dear Marie, Try this: combn(v,2,list) HTH, Jorge On Mon, Jun 8, 2009 at 8:56 AM, Marie Sivertsen mariesiv...@gmail.comwrote: Dear list, I have a vector of elements which I want to combined each with each, but none with itself. For example, v - c(a, b, c) and I need a function

Re: [R] Combining elements of vectors

one way is: combn(c(a, b, c), 2) I hope it helps. Best, Dimitris Marie Sivertsen wrote: Dear list, I have a vector of elements which I want to combined each with each, but none with itself. For example, v - c(a, b, c) and I need a function 'combine' such that combine(v) [[1]] [1] a

Re: [R] Combining elements of vectors

Thank you both Dimitiris and Jorge Ivan! I have just found it myself that 'combn' does what I need: combn(v, 2, simplify=TRUE) is exactly what I need. Mvh., Marie On Mon, Jun 8, 2009 at 3:03 PM, Dimitris Rizopoulos d.rizopou...@erasmusmc.nl wrote: one way is: combn(c(a, b, c), 2)
