## 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.
