ggs_histogram {ggmcmc}

Histograms of the paramters.

Description

Plot a histogram of each of the parameters. Histograms are plotted combining all chains for each parameter.

Usage

ggs_histogram(D, family = NA, bins = 30, 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).

bins

integer indicating the total number of bins in which to divide the histogram. Defaults to 30, which is the same as geom_histogram()

greek

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

Value

A ggplot object.
