\title{Plotting time-varying effects from a risk regression model.}
\usage{
plotEffects(
  x,
  formula,
  level,
  ref.line = TRUE,
  conf.int = 0.95,
  xlim,
  ylim,
  xlab = "Time",
  ylab = "Cumulative coefficient",
  col,
  lty,
  lwd,
  add = FALSE,
  legend,
  axes = TRUE,
  ...
)
}
\arguments{
\item{x}{Fitted object obtained with one of \code{ARR}, \code{LRR},
\code{riskRegression}.}

\item{formula}{A formula to specify the variable(s) whose regression
coefficients should be plotted.}

\item{level}{For categorical variables the level (group) whose contrast to
the reference level (group) should be plotted.}

\item{ref.line}{Logical. If \code{TRUE} then add a horizontal line at zero.}

\item{conf.int}{Logical. If \code{TRUE} then add confidence limits.  Can be
controlled using smart arguments. See examples}

\item{xlim}{See \code{plot}}

\item{ylim}{See \code{plot}}

\item{xlab}{See \code{plot}}

\item{ylab}{See \code{plot}}

\item{col}{A vector of colors for the regression coefficients.}

\item{lty}{A vector of line types for the regression coefficients.}

\item{lwd}{A vector of line thicknesses for the regression coefficients.}

\item{add}{Logical. If \code{TRUE} then add lines to an existing plot.}

\item{legend}{Logical. If \code{TRUE} then add a legend. Can be controlled
using smart arguments. See examples.}

\item{axes}{Logical. If \code{FALSE} then do not draw axes.}

\item{\dots}{Used for transclusion of smart arguments for \code{plot},
\code{axis}. See function \code{\link{SmartControl}} from prodlim.}

\examples{

library(survival)
library(prodlim)
data(Melanoma)

fit.tarr <- ARR(Hist(time,status)~strata(sex),
                data=Melanoma,
                cause=1)
plotEffects(fit.tarr)

fit.tarr <- ARR(Hist(time,status)~strata(sex)+strata(invasion),
                data=Melanoma,
                cause=1,
                times=seq(800,3000,20))
plotEffects(fit.tarr,formula=~sex)
plotEffects(fit.tarr,formula=~invasion)
plotEffects(fit.tarr,
            formula=~invasion,
            level="invasionlevel.1")

## legend arguments are transcluded:
plotEffects(fit.tarr,
            formula=~invasion,
            legend.bty="b",
            legend.cex=1)

## and other smart arguments too:
plotEffects(fit.tarr,
	    formula=~invasion,
	    legend.bty="b",
axis2.las=2,
	    legend.cex=1)
