Re: [R] return of a function

Thank you David, Jim and Gunter. Actually I knew about the list thing. Everything got confused in my head :-( I guess I am a bit tired... 2010/4/16 David Winsemius > > On Apr 16, 2010, at 12:02 PM, Gustave Lefou wrote: > > Dear R users, >> >> I have a function which takes as arguments big array

Re: [R] return of a function

You can return a single object from a function. If you want multiple values, use a list: f <- function(x,y,z){ return(list(x=x, y=y, z=z)) } value <- f(x,y,z) # now copy the values x <- value$x y <- value$y z <- value$z On Fri, Apr 16, 2010 at 12:02 PM, Gustave Lefou wrote: > Dear R use
