comparedens: Compare Density

In jagshelper: Extracting and Visualizing Output from 'jagsUI'

Compare Density

Description

Side-by-side kernel density plots for all parameters (or a specified subset) from two jagsUI output objects or data.frames. The intent of this function is easy comparison of inferences from two comparable models.

Kernel densities are plotted vertically, either left- or right-facing. Parameters with the same name are plotted facing one another.

Usage

comparedens(
  x1,
  x2,
  p = NULL,
  minCI = 0.99,
  ylim = NULL,
  legendnames = NULL,
  legendpos = "topleft",
  col = c(4, 2),
  ...
)

Arguments

x1	Output object returned from jagsUI; or alternately a data.frame
x2	Second output object returned from jagsUI; or alternately a data.frame
p	Optional vector of parameters to subset. All parameters with names matching the beginning of the string supplied will be returned. If the default (NULL) is accepted, all parameters will be plotted.
minCI	Minimum CI width for plotting. This is intended as a method for excluding far-outlying MCMC samples when determining the appropriate y-axis limits for plotting. Defaults to 99%.
ylim	Y-axis limits for plotting. If the default (NULL) is accepted, limits will be automatically determined.
legendnames	Names for optional legend. If the default NULL is accepted, no legend will be drawn.
legendpos	Position for optional legend. Defaults to "topleft".
col	Colors for kernel density plots. Defaults to colors 4 and 2 (blue and red).
...	additional plotting arguments

Value

NULL

Examples

## This is the same output object twice, but shows functionality.
comparedens(x1=asdf_jags_out, x2=asdf_jags_out, p=c("a","b","sig"),
            legendnames=c("Model 1", "Model 2"))
