The Form::radio() method works exactly the same as the Form::checkbox() method except that it automatically sets the type attribute to radio. The method only creates a single radio button so in order to create a group of buttons, just call the method more than once and use the same name.
echo Form::radio('name', 'yes', TRUE);
echo Form::radio('name', 'no', FALSE);
<input type="radio" name="name" value="yes" checked="checked" /> <input type="radio" name="name" value="no" />
The fourth parameter accepts an array of attributes
echo Form::radio('name', 'yes', TRUE, array('disabled'=>TRUE));
<input type="radio" name="name" value="yes" checked="checked" disabled="1" />
