Density plots of the chains
Density plots with the parameter distribution. For multiple chains, use colours to differentiate the distributions.
ggs_density(D, family = NA, rug = FALSE, hpd = FALSE, greek = FALSE)
D |
Data frame whith the simulations. |
family |
Name of the family of parameters to plot, as given by a character vector or a regular expression. A family of parameters is considered to be any group of parameters with the same name but different numerical value between square brackets (as beta[1], beta[2], etc). |
rug |
Logical indicating whether a rug must be added to the plot. It is FALSE by default, since in large chains it may use lot of resources and it is not central to the plot. |
hpd |
Logical indicating whether HPD intervals (using the defaults from ci()) must be added to the plot. It is FALSE by default. |
greek |
Logical value indicating whether parameter labels have to be parsed to get Greek letters. Defaults to false. |
A ggplot object.
