R help - Jun 2007 - Estimated coefficients from regsubsets/leaps: where are they?

Dear all,
	
	I am doing a simulation study to evaluate the performance of subset  
selections for linear regression.

	I need to:
	a) get the coefficients of the variables for each of the models  
selected along the way;
	b) at least get the logical matrix telling me which variables were  
selected at each step (notice that if I have a above, I can get this  
anyway...)
	
	The functions "summary" and "plot" can tell me which
variables are
selected (b above) but the on screen information is useless as I need  
to post-process the results in my simulation.
	I have unsuccessfully tried doing "names(regsubset_return_object)"  
and inspecting each of the fields in the object had anything that  
resembled the information I wanted.
	
	Does anyone knows how to do that?
	
	Thanks a lot,
	
	Guilherme
