plot.predint function

Plots of predint objects

This function provides methodology for plotting the prediction intervals or limits that are calculated using the functionality of the predint package.

## S3 method for class 'predint'
plot(x, ..., size = 4, width = 0.05, alpha = 0.5)

Arguments

• x: object of class predint
• ...: arguments handed over to ggplot2::aes()
• size: size of the dots
• width: margin of jittering
• alpha: opacity of dot colors

Returns

Since plot.predint() is based on ggplot2::ggplot, it returns an object of class c("gg", "ggplot").

Examples

### 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()
