\title{Plot method for npf_seir}
\usage{
\method{plot}{npf_seir}(x, burn = 0L, which = "Rt", dates = NULL, ...)
}
\arguments{
\item{x}{An \code{npf_seir} object.}

\item{burn}{Integer. Number of initial steps to exclude from the plot.}

\item{which}{Character. \code{"Rt"} (default), \code{"beta"}, or
\code{"both"} to show both trajectories in a two-panel display.}

\item{dates}{Optional Date vector with one entry per observation to use as
the x-axis.}

\item{...}{Additional arguments passed to \code{plot()}.}
}
\description{
Produces posterior summary plots for \eqn{R_t}, \eqn{\beta_t}, or both.
}
\value{
Returns \code{x} invisibly. Called primarily for its side effect of
producing a base-graphics plot. When \code{which = "Rt"} or \code{"beta"},
a single panel is drawn showing the posterior mean trajectory and 95\%
credible band. When \code{which = "both"}, a two-panel figure is produced
showing \eqn{R_t} (top) and \eqn{\beta_t} (bottom).
