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, densityplot plots the kernel density for the draws. For the frequentist lambda.reg method, densityplot plots the canonical Normal density conditional on the mean and standard error output by lambda.reg.

Usage

## S3 method for class 'lambdaMD'
densityplot(x, by = "column", col, xlim, ylim,
             main = "", sub = NULL, xlab, ylab,
             lty = par("lty"), lwd = par("lwd"), ...)
## S3 method for class 'lambdaRegBayes'
densityplot(x, by = "column", col, xlim, ylim,
             main = "", sub = NULL, xlab, ylab,
             lty = par("lty"), lwd = par("lwd"), ...)
## S3 method for class 'lambdaReg'
densityplot(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).
