I have created a library based on the Analytics helper posted by manilodisan. I made this into a library and added support for ecommerce tracking.
Usage:
In your controller.php
$this->load->library('Analytics_Lib');
//Add transaction detail to code
//add_trans('order_id','Company Name','Order Total','Tax','Shipping','City','State','Country');
$this->analytics_lib->add_trans('1234','Test Company','200','0','0','City','State','USA');
//Add order line item detail to code
//add_item('order_id','SKU','Product Name','Category','Price','Quantity');
$this->analytics_lib->add_item('1234','16-10','Test Product','Category','100','1');
//Generate entire Analytics javascript code
// @trackpage (optional)
// @UA-Account can be set in config $config['google_uacct']
//generate('trackpage','UA-Account');
$data['analytics'] = $this->analytics_lib->generate();
$this->load->view('page',$data);
In your view ie page.php
<html>
<head>
<title>Site Name</title>
<?php echo $analytics;?>
</head>
<body>
Body Goes Here
</body>
<html>
If you already copied and pasted the Analytics code from your Dashboard, you can add just the ecommerce snippets by the method show below:
In your controller.php
$this->load->library('Analytics_Lib');
//Add transaction detail to code
//add_trans('order_id','Company Name','Order Total','Tax','Shipping','City','State','Country');
$this->analytics_lib->add_trans('1234','Test Company','200','0','0','City','State','USA');
//Add order line item detail to code
//add_item('order_id','SKU','Product Name','Category','Price','Quantity');
$this->analytics_lib->add_item('1234','16-10','Test Product','Category','100','1');
//Generate only pageTracker._addTrans & pageTracker._addItem
$data['addTrans'] = $this->analytics_lib->getTrans();
$data['addItem'] = $this->analytics_lib->getItem();
$this->load->view('page',$data);
In your view page.php
<html>
<head>
<title>Site Name</title>
< script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
[removed](unescape("[removed][removed]"));

< script type="text/javascript">
try {
var pageTracker = _gat._getTracker("UA-XXXXXX-X");
pageTracker._trackPageview();
<?php echo $addTrans;?>
<?php echo $addItem;?>
} catch(err) {}[removed]
