there are R function with zero args : plot.new,frame, colors. In your case make sure that you list C is present in environments that you use.

Objet : [R] functions without arguments

hello,
I wanna know if it's possible to write functions without argument 
in order to understand that I write down an example

f <- function(){
 for (i in 1:length(C[[1]]) {
  print(10*C[[1]][i])
 }
}

I know that there are errors in this syntax
