R help - May 2009 - intermediate iterations of stepwise regression

Hi all,

I am performing a stepwise regression by running the "step" function
on
an "lm" object. Now I want to save the intermediate iterations. I know
the argument trace=T will print it on the console, but I rather want to 
assign it to some R object or may be output it in a CSV or text file.

Any help will be appreciated.

Regards
Utkarsh

Try this:

out <- capture.output(example(step))

You've received help in actually doing this.

Can I ask why you want to?

Stepwise selection is not a good method of model building.
