I get errors whenever I try to run the line for the plot:
library(glmmTMB)
model.gp <- glmmTMB(Grav~Age+Site+Educ+Occupation+Maritalstat+HIVpos,family = "genpois",data=bo)
library("countreg")
countreg::rootogram(model.gp)
Error in sqrt(as.vector(object)) : non-numeric argument to mathematical function In addition: Warning message: In rootogram.default(model.gp) : NAs introduced by coercion
I tried finding an appropriate function in the glmmmTMB package for plotting the rootogram() but I couldn't find one. I don't know if the problem could be the data or the package.
