Hello S-plus  Fans,

I am trying to extract the test of significants i.e probability of t,  from
a GLM.  When I use the summary function eg summary(glm(formula = y ~ b3,
family = quasi(link = identity, variance = constant), data =
resample.dist)), I only get a t value for the intercept and b3, see below:

Coefficients:
                 Value   Std. Error  t value 
(Intercept) 0.01296489 0.0007813802 16.59229
      b3 0.46420517 0.0104191808 44.55294

How can I:
1. get the Pr(t) for the intercept and b3
2. Extract the probability as a single number into a data frame

Your help is appreciated. Thanks

Cheers
