### PI for quasi-Poisson data
pred_int <- quasi_pois_pi(histdat=ames_HCD,
                          newoffset=3,
                          nboot=100,
                          traceplot = FALSE)

### Plot the PI
plot(pred_int)

### Since plot.predint is based on ggplot, the grafic can be altered using
# the methodology provided via ggplot2
plot(pred_int)+
     theme_classic()
