assign users to group modx

Question

How can i assign newly created user to the particular group in modx Programmaticaly ? Below is my code

if(isset($_POST) && count($_POST)){
  $oUser = $modx->newObject('modUser');
  $oUser->set('username', "test");
  //$oUser->set('password', "test");

  $oProfile = $modx->newObject('modUserProfile');
  $oProfile->set('fullname', $_POST['fname']);
  $oProfile->set('email', $_POST['email']);
  $oUser->addOne($oProfile);
  if($oUser->save()===false){
    echo "Error";
  }else
    echo "Done";
}

I googled but all i find is graphical tutorial how to create groups and edit user and then assign roles, If you know any tutorial then also its fine.

Here is how I have been doing it, this is a posthook snippet that fires after a user registers [and the user is created]

<?php
$specialty = $hook->getValue('specialty');
$country =  strtolower($hook->getValue('excountry'));
$username = $hook->getValue('username');
$staff = $hook->getValue('staff-or-resident'); //Staff | Resident

$joingroup = '';
$joinrole = '';
$blockuser = 'false';

switch ($specialty){

    case 'Other' :
        $joingroup = 15; // Other 
        $joinrole = 1; //member
        $blockuser = 'true';
        break;

    // there are about 15 different groups and roles here... 

    default :
        $joingroup = '0'; // none
        $joinrole = '0'; // none 
        break;  
}

if($joingroup > 0 && $joinrole > 0){
    $user = $modx->getObject('modUser', array('username'=>$username));
    $internalkey = $user->get('id');
    $profile = $user->getOne('Profile',array('internalKey'=>$internalkey));

    $user->joinGroup($joingroup, $joinrole);

    if($blockuser == 'true'){ //block user if they belong to the "other" group
        $profile->set('blocked',1);
    }

    if(!$user->save()){
        return false;
    };
}

return true;

The key is the: $user->joinGroup($joingroup, $joinrole); where joingroup is the group id ~ or name and the joinrole is the role id ~ or name. It's documented here: http://api.modx.com/revolution/2.1/_model_modx_moduser.class.html#%5CmodUser::joinGroup()
