Narrative:

When cleared for takeoff on runway 15L at iah, we were told to make a right turn to heading 360 degrees. The captain set the heading bug and we proceeded to take off. At 400 ft, the captain called for heading select, I pulled the knob and the v-bars were promptly followed. Error was not discovered until tower brought it to our attention. To avoid a recurrence, it would be best to set the heading bug for a r-hand turn of less than 180 degrees. Then, once well into the turn, set the bug to the desired heading (in this case, 360 degrees).
