\title{Plot method for sir-object}
\usage{
\method{plot}{sir}(
x,
conf.int = TRUE,
ylab,
xlab,
xlim,
main,
eps = 0.2,
abline = TRUE,
log = FALSE,
left.margin,
...
)
}
\arguments{
\item{x}{an object returned by function \code{sir}}
\item{conf.int}{default TRUE draws confidence intervals}
\item{ylab}{overwrites default y-axis label}
\item{xlab}{overwrites default x-axis label}
\item{xlim}{x-axis minimum and maximum values}
\item{main}{optional plot title}
\item{eps}{error bar vertical bar height (works only in 'model' or 'univariate')}
\item{abline}{logical; draws a grey line in SIR = 1}
\item{log}{logical; SIR is not in log scale by default}
\item{left.margin}{adjust left marginal of the plot to fit long variable names}
\item{...}{arguments passed on to plot(), segment and lines()}
}
\value{
Always returns \code{NULL} invisibly.
This function is called for its side effects.

\description{
Plot SIR estimates with error bars
}
\details{
Plot SIR estimates and confidence intervals
\itemize{
\item univariate - plots SIR with univariate confidence intervals
\item model - plots SIR with Poisson modelled confidence intervals
}
\strong{Customize}
Normal plot parameters can be passed to \code{plot}. These can be a vector when plotting error bars:
\itemize{
\item \code{pch} - point type
\item \code{lty} - line type
\item \code{col} - line/point colour
\item \code{lwd} - point/line size
}
\strong{Tips for plotting splines}
It's possible to use \code{plot} to first draw the
confidence intervals using specific line type or colour and then plotting
again the estimate using \code{lines(... , conf.int = FALSE)} with different
settings. This works only when \code{plot.type} is 'splines'.

\examples{
\donttest{
# Plot SIR estimates
# plot(sir.by.gender, col = c(4,2), log=FALSE, eps=0.2, lty=1, lwd=2, pch=19,
# main = 'SIR by gender', abline=TRUE)
}
