Hello everybody,

I have some problems with delta-gamma GLMM.

I have a data set with many zero of fish's density and I think it is better  to adopt a Glmm delta approach.
I have chosen to make a binomial glmm for the 0/1 values and a gamma glmm for positives values (it is a continuous variable).
My question is :  must it two plot of predict values ,one with binary data and one with positive data or is it possible to have one unique plot?

I use Glmer function and if is it possible what is the code for make a unique plot?

Thank's a lot
