Google analytics custom event tracker

event-tracker.js

var track  = function (args) {
        args = args || {};

        var category = args.category,
            action = args.action,
            label = args.label,
            value = args.value || null;

        if (_gaq) {
            _gaq.push(['_trackEvent', category, action, label, value]);
        }

var trackOutboundLink = function(link, category, action) {

        try {
		_gaq.push(['_trackEvent', category , action]);
	} catch(err){
                
	}
	setTimeout(function() {
		document.location.href = link.href;
	}, 100);

};


var trackReporting = function(e) {

	var tracking = document.getElementsByName('reportReason');

		var i = 0,
			length = tracking.length;

		for (i = 0; i < length; i++) {

			var r = tracking[i], id;

			if (r.checked) {

				id = r.id;

				track({
					category: 'post',
					action: 'report',
					label: id
				});

			}

		}
};


/*usage */
track({
      category: 'Deed',
      action: 'Submit',
      label: ''
      value: '' // Optional 
});

Maybe include an option to pass-in anobject for args.label and stringify it?
