plot_DPMst: Plot of a Dirichlet process mixture of skew t-distribution partition

Description

Plot of a Dirichlet process mixture of skew t-distribution partition

Usage

plot_DPMst(z, c, i = "", alpha = "?", U_SS, dims2plot = 1:nrow(z), ellipses = ifelse(length(dims2plot) < 3, TRUE, FALSE), gg.add = list(theme()), nbsim_dens = 1000, nice = FALSE)

Arguments

z
data matrix d x n with d dimensions in rows and n observations in columns.
c
allocation vector of length n indicating which observation belongs to which clusters.
i
current MCMC iteration number.
alpha
current value of the DP concentration parameter.
U_SS
a list containing "xi", "psi", "S", and "df".
dims2plot
index vector, subset of 1:d indicating which dimensions should be drawn. Default is all of them.
ellipses
a logical flag indicating whethe ellipses should be drawn around clusters. Default is TRUE if only 2 dimensions are plotted, FALSE otherwise.
gg.add
A list of instructions to add to the ggplot2 instruction. See +.gg. Default is list(theme()), which adds nothing to the plot.
nbsim_dens
number of simulated points used for computing clusters density contours in 2D plots. Default is 1000 points.
nice
logical flag changing the plot looks. Default is FALSE.
