function - R returning matrix -

-

I am trying to return a matrix from the function, but why it is unable to understand that it gives an error . 

  rdMatrix & lt; - Function (value = 0) {x & lt; - Get diag (value) & lt; - Function () Return (x) x}

Output: 

  & gt; Rdmatrix (5) [, 1] [, 2] [, 3] [, 4] [, 5] [1,] 0 0 [2,] 0 0 0 0 [3,] 0 0 0 0 0 [4,] 0 0 0 1 0 [5,] 0 0 0 1> Receives an error in RdMatrix $ get () rdMatrix $: object type 'closure' is not tabs & gt;  
 
        post-text "itemprop =" text "> 
 Perhaps you're aiming for:  
  rdMatrix <- Local ({get <- function () return (x) x & lt; - NULL function (value = 0) {x  
 
 Or maybe you prefer : 
 
  rdMatrix & lt; - local ({x <-> NULL list (get = function) returns (x), set = function (value = 0) {x < & Lt; - diag (value)})} rdMatrix $ set (3) rdMatrix $ get ()

For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
