half-normal waste graph Plots no ggplot2

Question

I am trying to realize the graph presented below regarding the residues in the half-normal Plot in ggplot2.

However, I am facing an error entitled Error: data must be a data frame, or other Object coercible by fortify(), not an S3 Object with class hnp.

The data can be seen below.

Stones <- c(rep("Stone1",1), rep("Stone2",1), rep("Stone3",1))
treat <- c(rep("T6",9), rep("T7",9), rep("T8",9), 
           rep("T10",9), rep("T11",9),
           rep("T12",9),rep("T14",9),rep("T15",9),
           rep("T16",9))
Samples <- c(rep("SampleI",3), rep("SampleF",3), rep("SampleR",3))
Count <- c(3,3,1,1,2,2,0,0,0,1,2,3,0,0,1,0,0,0,2,0,2,2,0,0,0,0,0,6,
           1,0,2,2,2,0,0,0,4,4,1,3,2,5,0,0,0,3,4,4,5,1,2,0,0,0,
           4,4,6,1,2,1,0,0,0,4,6,4,2,3,1,0,0,0,3,2,2,1,0,5,0,1,0)
Total <- c(rep("6", 81))
dados <- data.frame(treat, Stones, Samples, Count, Total);dados
dados$treat = as.factor(dados$treat)
dados$Samples = as.factor(dados$Samples)
dados$Total = as.numeric(dados$Total)
dados$Prop = dados$Count/dados$Total
dados16 = dados[dados$treat=="T16",];dados16`

The model adjustment is shown below.

resp16 <-cbind(dados16$Count,dados16$Total - dados16$Count); resp16
m16 <- glm(resp16 ~ Samples,
           data = dados16,
           family = quasibinomial)

Graph16=hnp(m16, xlab = 'Percentil da N(0,1)', ylab = 'Resíduos', 
    main = 'Gráfico Normal de Probabilidades')

The error is here.

ggplot(data = Graph16)
Erro: `data` must be a data frame, or other object coercible by `fortify()`, not an S3 object with class hnp

Answer 1

According to the section Value of help("hnp), the object Graph16 is a class list "hnp". These objects have members x, lower, upper, median and residuals, which are the vectors represented in the graph. First you have to create a data.frame with these vectors and then plot the graph.

library(ggplot2)

G16 <- with(Graph16, data.frame(x, lower, upper, median, residuals))
G16

ggplot(data = G16, aes(x)) +
  geom_point(aes(y = residuals)) +
  geom_line(aes(y = lower)) +
  geom_line(aes(y = upper)) +
  geom_line(aes(y = median), linetype = "dashed")
