Qq plot of randomized quantile residuals against standard normal quantiles

Description

Qq plot of randomized quantile residuals against standard normal quantiles

Usage

residqq(
  umFit,
  type = "site-sum",
  main = "Residual qq plot",
  plotLine = TRUE,
  ...
)

Arguments

umFit	An object of class unmarkedFit from a model fitted using pcount.
type	The type of randomized quantile residual to plot. One of 'site-sum' or 'observation'.
main	Plot label.
plotLine	If true, the identity line is added to the plot.
...	Further arguments passed to qqnorm.

Value

A list with x and y coordinates of the qq plot, see qqnorm.

Examples

library(unmarked)
umf = unmarkedFramePCount(y = shoveler$y, obsCovs = shoveler$obs, siteCovs = shoveler$site)
fmP = pcount(~scale(date) + scale(reedcover) ~ scale(log(water)) + scale(latitude), 
      data = umf, K = 80)
residqq(fmP, "site-sum")
residqq(fmP, "observation")
