what |
Character indicating what parameters to plot.
Possible values are |
scales |
Character vector of length two, with possible values "same" or
"free", indicating whether x- and y-axes of the plots should be
constrained to be the same across panels. For |
layout |
Character. If |
aspect |
How should the panels be scaled. Default ( |
check |
Logical. Should the density plots be separate for each chain (in order to check convergence) or should the chains be merged. |
lwd |
Width of the lines used for plotting of the posterior densities. |
col |
Color of the lines points used for plotting of the posterior densities. |
plot.points |
Logical. Should a rug with actual data points be plotted beneath the density. |
pch |
Plot symbol for the points. |
subset |
Character or numerical indicating the columns of the posterior
that should be plotted by |
cex |
Plot character size for points in |
