[R] test for coeff. differences

[Tord Snall]

Dear all,

Is there a function in R for test of pairwise differences in point
estimates of a binomial glm?. The variance-covariance matrix, vcov() in
MASS, shows that there is some non-orthogonality.

I use R 1.2.2 for WinNT.

Thanks in advance!


Sincerely,
Tord Snäll
