Subject: [R] return of a function

Dear R users,

I have a function which takes as arguments big arrays, say : w, x , y and z.

My function changes these arrays and I want them as result/output.

I have tried to write return(w,x,y,z), and thus to replace the previous w,
x, y and z. It does not seem to work.

What can I do ?

-- 1. Read the Help file? -- which says:

return(value)

Arguments:

value: An expression. 

-- and note that w,x,y,z is **not** a legal R expression

2. Have you read the online documentation, including an Introduction to R?
There you would find many examples.

3. return(list(w,x,y,z))   ## is what you want 
## or even 
list(w,x,y,z) ## without the return(), as the last R expression is by
default what is returned.




Thank you very much,
Gustave
