Plot posterior predictive check

Description

Plots a series of graphical posterior predictive checks for a map or map2stan model fit.

Usage

postcheck( fit , prob=0.9 , window=20 , n=1000 , col=rangi2 , ... )

Arguments

fit	A map or map2stan model fit
prob	Width of prediction interval to display
window	Number of cases to display in each plot (for paging)
n	Number of samples from posterior to use
...	Additional arguments to pass to plot
