ggplot_number_of_clusters_trace {tip}

Plot the trace plot of the posterior number of clusters

Description

A function that produces a ggplot2 trace plot (i.e., geom_line) with respect to the posterior number of clusters.

Usage

ggplot_number_of_clusters_trace(.posterior_number_of_clusters)

Arguments

.posterior_number_of_clusters

Vector of positive integers: each (s)th element denotes the number of clusters after posterior sampling for each iteration s = 1, 2, ..., samples + burn in the Gibbs sampler.

Value

ggplot2 geom_line plot: a plot of the posterior number of clusters in each Gibbs sampling iteration versus the Gibbs sampling iteration number.

Examples

# Import the tip library
library(tip)

# Generate a vector of positive integers
# Example: the posterior number of clusters computed after posterior
# sampling in each sampling iteration of the Gibbs sampler.
num_clusters <- c(1,2,2,2,2,3,3,1,2,3,3,3,1,3)

# Generate the plot of the posterior number of clusters versus the
# sampling iteration number in the Gibbs sampler.
ggplot_number_of_clusters_trace(.posterior_number_of_clusters = num_clusters)
