This video is not working. You should check the link.

Take the following comment as a constructive suggestion since you post a lot of these under the tag tutorial. If you are going to the trouble of creating a video would it be possible to talk about the topic at hand as you walk people through the method/steps. There is no explanation of why you are doing something on screen in a couple three videos I checked. A rounded tutorial needs to adequately educate users and not just teach them where to click in a program. If you prefer not to speak then you could switch back and forth between a set of slides and R.
