Below is a summary on returning variable from subfunction, Thanks to 
Brian Ripley and Douglas Bates:

To access the variables within a function, return a list or data structure 
assigned to a variable in the calling function. For more than one varaible, 
assign them to a list variable and separate the components in the calling 
function using listname$variablename.

"test" <-
    function()
  {
    "hello" <-
      function()    
        {
          x <- 1:3
          y <- 23:34
          z <- cbind(x,y)
          return(x,y,z)              
        }
    c <- hello()
    return(c$z,c$x, c$y)
  }
