plotPoster: Plots posterior densities.

In markvdwiel/ShrinkBayes: Bayesian analysis of high-dimensional omics data, either Gaussian or counts

Plots posterior densities.

Description

Plots posterior densities, possibly including a posterior null point mass.

Usage

plotPoster(id, poster, miny = 10^(-4), xlabel = "", ylabel = "", plotlabels = NULL, cols = NULL, ltys = NULL,lwds =NULL, xran = NULL, 
xscatter = NULL, legendxy = NULL, legendbox = "n", include0 = TRUE)

Arguments

id	Integer. Index of feature for which the posterior density is desired
poster	A list of lists where each sublist contains posteriors of (possibly) multiple parameters (or linear combinations) from the same data. A posterior is represented as a matrix with two columns denoting support and posterior density.
miny	Numeric. Minimum value of density (in the tails)
xlabel	Character. Label for the x-axis.
ylabel	Character. Label for the y-axis.
plotlabels	Character vector. Label(s) for the graphs.
cols	Numerical or character vector. Colours of the graphs.
ltys	Numerical or character vector. Line types for the graphs.
lwds	Numerical vector. Line widths for the graphs.
xran	Numerical 2-component vector. Range for the x-values.
xscatter	Numeric. Scatter for the null point masses.
legendxy	Numerical 2-component vector. Determines (x,y)-location of the legend.
legendbox	Character. If legendbox="n" no legend box is drawn; if legendbox="o" a legend box is drawn.
include0	Boolean. include0=TRUE the null point mass is drawn as well.

Details

About posteriorlist: this usually results from NonParaUpdatePosterior, MixtureUpdatePosterior, BFUpdatePosterior or SpikeSlabUpdatePosterior. About xscatter: when multiple densities are displayed in one figure, the null point masses overlap. Hence, a small scatter is added to avoid the overlap.

Value

Plot.
