ggs_caterpillar: Caterpillar plot with thick and thin CI

Description

Caterpillar plots are plotted combining all chains for each parameter.

Usage

ggs_caterpillar(D, family = NA, X = NA,
    thick.ci = c(0.05, 0.95), thin.ci = c(0.025, 0.975),
    line = NA, horizontal = TRUE, labels = NULL)

Arguments

D

Data frame whith the simulations or list of data frame with simulations. If a list of data frames with simulations is passed, the names of the models are the names of the objects in the list.

X

data frame with two columns, Parameter and the value for the x location. Parameter must be a character vector with the same names that the parameters in the D object.

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[

thick.ci

Vector of length 2 with the quantiles of the thick band for the credible interval

thin.ci

Vector of length 2 with the quantiles of the thin band for the credible interval

line

Numerical value indicating a concrete position, usually used to mark where zero is. By default do not plot any line.

horizontal

Logical. When TRUE (the default), the plot has horizontal lines. When FALSE, the plot is reversed to show vertical lines. Horizontal lines are more appropriate for categorical caterpillar plots, because the x-axis is the only dimension that matter

labels

Vector of strings that matches the number of models in the list. It is only used in case of multiple models and when the list of ggs objects given at D is not named. Otherwise, the names in the list are used.

Value

• A ggplot object.

Examples

data(samples)
ggs_caterpillar(ggs(S, parallel=FALSE))
ggs_caterpillar(list(A=ggs(S, parallel=FALSE), B=ggs(S, parallel=FALSE))) # silly example duplicating the same model
