Maybe there is a great website out there or white paper that discusses this but again my Google skills (or lack there of) let me down. I would like to know the best way to export several doubles from a function, where the doubles are not an array. Here is a contrived function similar to my needs: multipleoutput<-function(x) { squared<-x^2 cubed<-x^3 exponentioal<-exp(x)

...xp(x))) } But then you'd have to call it like so: > mapply(multipleoutput, c(0,1,2))        [,1]     [,2]     [,3] square    0 1.000000 4.000000 cube      0 1.000000 8.000000 exp       1 2.718282 7.389056 If you call it like so: > multipleoutput(c(0,1,2)) square1  square2  square3    cube1    cube2    cube3     exp1     exp2 0.000000 1.000000 4.000000 0.000000 1.000000 8.000000 1.000000 2.718282     exp3 7.389056 then R flattens the result.  Weird. - Godmar ------------------------------ Message: 131 Date: Thu, 9 Jul 2009 00:35:08 +0100 From: tzygmund mcfarlane <tzygmund@go...
