[R] GLM Contingency table regressions

I have a contingency table with a 0/1 variable (fwr) that flags a particular
condition, a weight variable (cnt) and other variables (e.g. zz)
characterizing that observation of the table.
I am trying to use GLM. By converting the variables to factors and running
the following regression:
fwr1<-factor(fwr)
zz1<-factor(zz1)
res1<-glm(fwr1 ~ zz1,weights=cnt)

Is that appropriate?
