[R] glmmPQL and random effects

Hello R users,

I am trying to run a model with a binary response variable (nesting success: 0 failure, 1 success) and 8 fixed terms. Nesting success was examined in 72 cases in 34 territories (TER) during a 6 study years. Territories are nested within 14 patches (PATCH). I want to run a model taking into account these nested factors and repeated observation. To do this, I assume that the best option is to use glmmPQL from MASS package. Am I wrong?

In glmmPQL, I have included the random terms as follow: random=~1|YEAR/PATCH/TER, but I am unclear if this syntax is right for this case (?).

I would greatly appreciate any help!

Regards,

Hugo
