ggs_compare_partial {ggmcmc}

Density plots comparing the distribution of the whole chain with only its last part.

Description

Density plots comparing the distribution of the whole chain with only its last part.

Usage

ggs_compare_partial(D, family = NA, partial = 0.1, rug = FALSE, greek = FALSE)

Arguments

D

Data frame whith the simulations

family

Name of the family of parameters to plot, as given by a character vector or a regular expression. A family of parameters is considered to be any group of parameters with the same name but different numerical value between square brackets (as beta[1], beta[2], etc).

partial

Percentage of the chain to compare to. Defaults to the last 10 percent.

rug

Logical indicating whether a rug must be added to the plot. It is FALSE by default, since in large chains it may use lot of resources and it is not central to the plot.

greek

Logical value indicating whether parameter labels have to be parsed to get Greek letters. Defaults to false.

Value

A ggplot object.
