## Density plots for population level parameters

### Description

Generates a density plot for population level quantities of interest output by `lambda.MD`, `lambda.reg`, and `lambda.reg.bayes`. For the Bayesian methods, `density.plot` plots the kernel density for the draws. For the frequentist `lambda.reg` method, `density.plot` plots the canonical Normal density conditional on the mean and standard error output by `lambda.reg`.

### Usage

    density.plot(x, by = "column", col, xlim, ylim,
                 main = "", sub = NULL, xlab, ylab,
                 lty = par("lty"), lwd = par("lwd"), ...)

### Arguments

`x` | output from `lambda.MD`, `lambda.reg`, or `lambda.reg.bayes`.
`by` | character string (defaulting to `"column"`) specifying whether to panel the density plot by `"row"` or `"column"` marginal.
`col` | an optional vector of colors, with length corresponding to the number of marginals selected in `by`. Defaults to `rainbow`.
`xlim,ylim` | optional limits for the x-axis and y-axis, passed to `plot`.
`main,sub` | optional title and subtitle, passed to `plot`.
`xlab,ylab` | optional labels for the x- and y-axes, passed to `plot`.
`lty,lwd` | optional arguments for line type and line width, passed to `lines` and `plot`. If either `lty` or `lwd` are vectors, it must correspond to the number of row or column marginals selected.
`...` | additional arguments passed to `par`.

### Value

A plot with density lines for the selected margin (row or column).
