In rms: Regression Modeling Strategies

plot.contrast.rms

Description

Plot Bayesian Contrast Posterior Densities

Usage

## S3 method for class 'contrast.rms'
plot(
  x,
  bivar = FALSE,
  bivarmethod = c("ellipse", "kernel"),
  prob = 0.95,
  which = c("both", "diff", "ind"),
  nrow = NULL,
  ncol = NULL,
  ...
)

Arguments

x	the result of contrast.rms
bivar	set to TRUE to plot 2-d posterior density contour
bivarmethod	see rmsb::pdensityContour()
prob	posterior coverage probability for HPD interval or 2-d contour
which	applies when plotting the result of contrast(..., fun=), defaulting to showing the posterior density of both estimates plus their difference. Set to "ind" to only show the two individual densities or "diff" to only show the posterior density for the differences.
nrow	for ggplot2::facet_wrap()
ncol	likewise
...	unused

Details

If there are exactly two contrasts and bivar=TRUE plots an elliptical or kernal (based on bivarmethod posterior density contour with probability prob). Otherwise plots a series of posterior densities of contrasts along with HPD intervals, posterior means, and medians. When the result being plotted comes from contrast with ⁠fun=⁠ specified, both the two individual estimates and their difference are plotted.

Value

ggplot2 object
