Set checkbox values to true

I am displaying a list of items using the selectcheckboxes in a manner virtually identical to the example from the VisualForce documentation on page 210 as reflected below.

 

I am interested in checking some of the checkboxes as they are displayed, without user input.  What code would need to be added to this example in order for my checkboxes to appear checked as they are being displayed?

 

Thanks in advance for your help.

 

Jeff
