I'm running through MMI for my data this is only one giving me problems
(again all of the above script works fine with *exactly* same GAM model with
a poisson distribution!)

Hi,
I have a GAM quasipoisson that I'd like to run through MuMIn package
- dredge
- gettop.models
- model.avg
However, I'm having no luck with script from an example in MuMIn help file.
In MuMIn help they advise "include only models with smooth OR linear term
(but not both) for each
*Warning messages: *appear after dredging global model in MMI and
requesting model selection table
dd(global model)<-dredge(global model) - runs OK
dd(global model)
* 1: In x[i] <- value[[j]] :
number of items to replace is not a multiple of replacement length*
Also at model averaging stage
t AIC with this model)
- glmm in lme4 (lmer) - won't allow variance structure
- gls - can add variance but can't have Poisson
Thanks so much,

WDLD:DISTWOOD :
# numerical expression has 150 elements: only the first used
Can anyone offer advice on how to include this interaction in GAMM model?
Thanks
