Is names(model1$coef) what you're looking for?

Subject: [R] Obtaining the variable names of a glm object
Hi, R users!
Suppose I make a model like this:
model1<-glm(resp~var1+var2+factor1+factor2+var1:factor1+var1:factor1+var2:factor2+var2:factor2,family=poisson)
where "resp" is a response variable (poisson distributed) "var1" and "var2" are continuous variables and "factor1" and "factor2" are nominal variables (here I use them as
dummy variable)
"factor1" has 2 levels (2 and 8) and "factor2" 3 levels ( 1, 6 and 12). Now I want to obtain the labels of the coeficients of the model in 3
separate columns and a
4th column with the corresponding value,
like this:
variable1 variable2 level value
(intercept) X
var1 X
var2 X
factor1 8 X
factor2 6 X
factor2 12 X
var1 factor1 8 X
var1 factor2 6 X
var1 factor2 12 X
var2 factor1 8 X
var2 factor2 6 X
var2 factor2 12 X
If I use:
model1$coef, I obtain the name of the coef, but joined.
I want them separated.
Thank you very much for your help!!!
