I tried to run a GLM model using S-Plus and R. The same model and data were 
applied to the both packages. I got different results of  P(>|Chi|) for Anova, 
between S-PLus and R. Other estimates values are the same. 

P(>|Chi|) for S-Plus:
0.99565 0.99682 0.04871 0.84597 1.00000 0.99999 1.00000 1.00000 1.00000 0.95834

P(>|Chi|) for R:
0.00000 0.00000 0.00000  0.00000 0.00000 0.00000 0.00350 0.26400 0.46800 0.0000

I used S-Plus 6.1 for windows, Profesional Edition release 1, and R 1.8.1.

Does anyone have any idea how this could happen? 

Thank you very much for your time.
