Heres an example using the User Datamanager

PHP Code:

$someuserid = 62;
$someuserinfo = fetch_userinfo($someuserid);

// $userdm = datamanager_init('User'...
$userdm->set_existing($someuserinfo);
$userdm->set('username', 'SomeotherName');

$userdm->save(); 


So you use the set_existing() function of the datamanger then just set the bits you want changed.
