change publish rate of a topic

Is there any way to change the rate at which messages are published?

Edit: To update with more information. I would like to know all ways to throttle a node without using programming practices that don't involve the ROS Api. E.g nothing that does (if loop_count % 5) -> Publish(msg)

  1. How to throttle the topic via roslaunch
  2. via command line ROS commands
  3. via ROS api

Thanks!
