A suggestion for predict function(s)

From: Liaw, Andy

From: Ross Darnell 

A good point but what is the value of storing a large set of 
predicted 
values when the values of the explanatory variables are lost 
(predicted 
values of what?). I thought the purpose of objects was that 
they were 
self explanatory (pardon the pun).

Maybe we could make it optional.
If what you are looking for is a way to track the 
observations, I'd suggest
simply adding rownames of newdata as names of the predicted 
values.  Storing
names is much cheaper than the entire data frame of 
predictors.  (And in R,
data frames _must_ have unique row names.)
And as a matter of fact, predict.lm() and predict.glm() 
(and probably most other predict() methods) already do 
that.

Andy
Cheers,
Andy
