I ended up figuring it out. ->setValue does do the trick but it wasn’t working for me because I wasn’t using the formRadio view helper to print out the element. I wrote my own custom one and forgot to print out the $checked variable in my element’s markup.

Have you tried ->setAttribute(‘checked’, ‘checked’). Although I’m guessing this will check the first radio button.

A better way to set the ‘value’ attributes is to pass an associative array to addMultiOptions, ie

->addMultiOptions(array(
‘true’ => ‘by frequency’,
‘false’ => ‘alphabetically’
))
