Please don't repeat post. In fact, you should definitely read the Posting Guide mentioned at the bottom if this or any other post from the list and follow its advice.

The usual way to predict output of a model in R is to use the predict function appropriate to your model object class. You might find reading the help file ?predict.glm helpful. If not, then you might be needing to study some more basic use cases of R so you can interpret the help files.
