    The following HTML file shows how you can do this:

    <html>
  <head>
    <script type="text/javascript" src="jquery-1.2.6.pack.js"></script>
    <script type="text/javascript">
      $(document).ready(function(){
        $("a").click(function(event){
          $("input[name='Foo'][value='All']").attr('checked','checked');
          event.preventDefault();
        });
      });
    </script>
  </head>
  <body>
    <ul>
      <li><input type="radio"  value="All"  name="Foo"  />All</li>
      <li><input type="radio"  value="New"  name="Foo"  />New</li>
      <li><input type="radio"  value="Removed"  name="Foo"  />Removed</li>
      <li><input type="radio"  value="Updated"  name="Foo"  />Updated</li>
    </ul>
    <a href="" >Click here</a>
  </body>
</html>

    When you click on the link, the desired radio button is selected. The important line is the one setting the checked attribute.

    I was beating my head against a wall similar to this and just want to point out that in jQuery 1.3 the syntax used in the accepted answer is the ONLY syntax that will work. The questioner uses the @ syntax for the expression which does not work at all in jQuery. Hopefully this helps the next guy to come across this question via Google =p

    To be clear, you have to use 

    jQuery('input[name=field1][val=checked]')

    and not 

    jQuery('input[@name=field1][@val=checked]')
