AIC model selection

The last time I used it, the function step() was using
AIC as model selection criteria as the default. It is
in the base package so you don't have to refer to
other fancy functions.

Are you looking for possibly stepAIC from the

Hello All;

I need to run a multiple regression analysis and

use Akaike's Information 

Criterion for model selection.  I understand that

this command will give the 

AIC value for specified models:

AIC(object, ..., k = 2)

with "..." meaning any other optional models for

which I would like AIC 

values.  But, how can I specify (in the place of

"...") that I want R to 

perform an model selection prodecure based on

Akaike's Information Criterion 

on a set of potential independent variables in a

model such as:

model.lm=lm(A~B+C+D+E+F+G)

?

Thanks a million;

Marty
