Allocate resources to new role programmatically in Magento

suppose you create new supplier role from System > Permission

Now I will assign specific or limited resources  to supplier role through some stuff.

suppose supplier id = 2

 Mage::getModel('admin/rules')
            ->setRoleId(2) // 2 is supplier id
            ->setResources(array('admin/catalog','admin/catalog/products','admin/seller_dashboard','admin/system','admin/system/myaccount',
                            'admin/seller','admin/seller/orders','admin/seller/reviews'))
            ->saveRel();

Any query about this Answer ask me ?
