cover.plot: Unit-level coverage plots for beta parameters from MD EI model

Description

Generates a plot of central credible intervals for the unit-level beta parameters from the Multinomial-Dirichlet ecological inference model (see ei.MD.bayes).

Usage

cover.plot(object, row, column, x = NULL, CI = 0.95, medians = TRUE, col = NULL, ylim = c(0,1), ylab, lty = par("lty"), lwd = par("lwd"), ...)

Arguments

object
output from ei.MD.bayes
row
a character string specifying the row marginal of interest
column
a character string specifying the column marginal of interest
x
an optional covariate to index the units along the x-axis
CI
a fraction between 0 and 1 (defaults to 0.95), specifying the coverage of the central credible interval to be plotted for each unit
medians
a logical value specifying whether to plot the median (defaults to TRUE). If medians = FALSE, the medians are not plotted.
col
an optional vector of colors to be passed to plot and segments. If col is of length two, then the first color is used for plot and the second for segments.
ylim
an optional range for the y-axis (defaults to c(0,1)).
ylab
an optional label for the y-axis (defaults to Proportion of row in column).
lty
an optional line type passed to segments.
lwd
an optional line width argument passed to segments.
...
additional arguments passed to plot.

Value

A plot with vertical intervals indicating the central credible intervals for each ecological unit.
