[R] regression/step coefficients extraction

I'm looking for a way to easily extract regression p-values and export
them to one file for further evaluation.
Here is the problem.
I use lm() and step() to get my regression parameters/coefficients.
after that I can extract them with summary(lm-results)$coefficients[,4]
so far so good
but it seems that if a value is not significant it is dropped from the
table/matrix so the previous command yields no consistent results with
respect to the order of appearance.
so I can get p-values for one regression being:
a b c d
.01 .01 .01 .01
and the next
a b d
.01 .01 .01
so it's not easy to match them up correctly, because these shifts in
order or the lack of NA or empty spaces.
I would like an output to text file in this form
independent parameters: a b c
p-values: .01 .02 .01
.01 NA .01
Any ideas to get a nice (and easy) output file where the dropped values
are filled in with NA and keeping the order and labels ok... ?
