[R] Fit values for NA's in linear regression

[Luca Wacker]

Hi,

To obtain estimates for some missing values in my data I fitted a 
linear regression and then used the command fitted(model) to get the 
fitted values from the model, but R doesn't return any values for the 
NA's. I can calculate the fitted values from the estimates obtained 
from the summary of model, but that's not very handy. Is there a way to 
include the missing values in the analysis and get fitted values for 
the NA's? I tried to use with the function na.action, but that didn't 
work.


thanks

Luca
