violinplot {sparsereg}

Function for plotting posterior distribution of effects of interest.

Description

The function produces a violin plot for specified effects. This can be useful for presenting or examining particular marginal effects of interest.

Usage

violinplot(x, columns=NULL, newlabels=NULL, type="mode", stage=NULL)

Arguments

x

Object of class sparsereg.

columns

A vector of numbers (or strings) corresponding to columns (or column names) to produce plots for.

newlabels

New labels for columns rather than variable names in object. If empty, variable names are used.

type

Options are "mode" and "mean". Whether to plot the posterior mode or mean.

stage

Currently, this argument is ignored.

Details

Generates a violin plot for coefficients from object from class sparsereg. The desired coefficients can be requested using the columns argument and they can be assigned new names through newlabels.
