Extracting p-values from modeling

Hello,

  I have being conducting some (conditional logistic) regressions
(clr), and I'm interested in extracting and manipulating (as a number)
the p-values.  (This is a prelude to some power simulations, where I'll
generate data sets, perform a clr on each data set, and then extract the
p-value for calculation of the power.)  From what I can tell, the
p-value is not one of the quantities for which there is a predefined
variable for extraction (such as coef), and I haven't yet been able to
extract the p-value (or anything) from the modeling object or its
summary.

  Is there any command for what I want to do, or some workaround?

  Thanks so much.
