[R] GLM outputs in condensed versus expanded table

[francogrex]

Hi I'm having different outputs from GLM when using a "condensed" table
V1	V2	V3	Present	Absent
0	0	0	3	12
0	0	1	0	0
0	1	0	0	0
0	1	1	1	0
1	0	0	7	20
1	0	1	0	0
1	1	0	3	0
1	1	1	6	0


resp=cbind(Present, Absent)
glm(resp~V1+V2+V3+I(V1*V2*V3),family=binomial)
>Deviance Residuals: 
[1]  0  0  0  0  0  0  0  0
 etc and also coefficients...

And when using the same but "expanded" table

	V1	V2	V3	condition (1 present 0 abscent)
Id1	1	0	0	1
id2	1	1	1	1
... etc
glm(condition~V1+V2+V3+I(V1*V2*V3),family=binomial)
>Deviance Residuals: 
        Min          1Q      Median          3Q         Max  
  -0.7747317  -0.7747317  -0.6680472   0.0001315   1.7941226 
and also coefficients are different from above.

What could I be doing wrong?
