R help - Aug 2010 - Retrieving predictions after fitting a model

Hi there

I am trying to retrieve the predicted values after fitting a model (dose
response model). How do I do it. What is the code for it? For estimated
parameters, one uses : summary(filename). And for the predicted values, what
do I use? Many thanks.

  It depends on the model, but try

predict()

and/or

fitted()

  (See the generic help pages ?predict and ?fitted, also possibly
the specific help pages corresponding to your model type, for example
?predict.glm)

  If you need more detail, you're going to have to give us more detail
about what you did.
