Delta aproach for binomial data with a lot of zeros

#1
Dear friends,

I will like to ask if someone ever used any package in R to model binomial glm for the presence-absence representation of the data, and a continuous distribution such as Gamma glm for the positive values.
Does someone knows any good package for such analysis?

Thanks
P

Thank you for your answer but I cant work with zero inflated models since my data are continuous with a lot of zeros and not counts.
I was thinking to apply something similar like hurdle models.

From other posts some people are using the tweedie package and to run my analysis. anyone ever used it for similar purposes?
