[R] Organize regression output

[francesca Pancotto]

Dear Contributors

I would like to ask some help concerning the automatization process of an analysis, that sounds hard to my knowledge.
I have a list of regression models. 
I call them models=c(ra,rb,rc,rd,re,rf,rg,rh)

I can access the output of each of them using for example, for the first

ra$coefficients

and i obtain

(Intercept)       coeff1          coeff2            age      		gender  
 0.62003033  0.00350807 -0.03817848 -0.01513533 -0.18668972
and I know that ra$coefficients[1] would give me the intercept of this model.

What i need to do is to collect the coefficients of each regression in models, and calculate and place in a table, the following simple summation:


ra						rb	 						rc      ...

intercept					intercept					intercept
intercept+coeff1			intercept+coeff1			intercept+coeff1
intercept+coeff2			intercept+coeff2			intercept+coeff2
intercept+coeff1+coeff2		intercept+coeff1+coeff2		intercept+coeff1+coeff2


The calculations are trivial(I know how to do it in steps) but what is difficult for me is to invent a procedure that organizes the data in an efficient way.

I tried some step , starting with collecting the coefficients but i think I am going the wrong way

calcolati <- list()
for (i in c(ra,rb,rc,rd,re,rf,rg,rh))
{
  calcolati[[i]] <- i$coefficients[1]
}

Thanks for any help you can provide.
