I am using SharePoint 2013 REST to show data from my list,

one of my field in announce list is AnnouncedBy which is a user packer field

or is a lookup field 

how can I display it or get it using SharePoint 2013 REST?

```
 var app = angular.module('SmartphoneOSList', ['ngSanitize']);  
 app.controller('ListController', function ($scope, $http) {  
 $http({  
    method: 'GET',  
    url: "https://myserver/_api/web/lists/getByTitle('announce')/items?$top=2&$orderby=Modified desc",  
    headers: { "Accept": "application/json;odata=verbose" }  
   }).success(function (data, status, headers, config) {  
     $scope.items = data.d.results;  

   }).error(function (data, status, headers, config) {  
    //...
    });  
});

```
