Examples

set.seed(1)
data(friend)

##  Fit an association model with homogeneous row-column effects
rc1 <- gnm(Freq ~ r + c + Diag(r,c) + Nonlin(MultHomog(r, c)),
           family = poisson, data = friend)
rc1

##  Extend to two-component interaction (using workaround)
original <- as.data.frame(friend)
r2 <- original$r
c2 <- original$c
rc2 <- update(rc1, . ~ . + Nonlin(MultHomog(r2, c2)))
rc2
