Example library(glmmTMB) library(ggeffects) ## Zero-inflated negative binomial model (m <- glmmTMB(count ~ spp + mined + (1|site), ziformula=~spp + mined, family=nbinom2, data=Salamanders,...

I am using the glmmTMB library to run mixed models, within a R markdown document. Any model that I run, I get these warnings: 'giveCsparse' has been deprecated; setting 'repr = "T"' for y...

I have semicontinuous data (many exact zeros and continuous positive outcomes) that I am trying to model. I have largely learned about modeling data with substantial zero mass from Zuur and Ieno's ...

I'm running R 4.02 and RStudio 1.3.1073. I'm having an error when I'm running a model with glmmTMB. Should I update or revert to a different version? Error in .Call("FreeADFunObject", pt...

I am trying to manually plot model estimates on top of data. My real problem is far more complicated than this, so I want to avoid using predict if I can, and would prefer to understand how these p...
