\arguments{
  \item{x}{an \code{stpm2} object}
  \item{newdata}{required list of new data. This defines the unexposed
    newdata (\emph{excluding} the event times).}
  \item{type}{specify the type of prediction
  }
  \item{col}{line colour}
  \item{lty}{line type}
  \item{ci.col}{confidence interval colour}
  \item{ci}{whether to plot the confidence interval band (default=TRUE)}
  \item{rug}{whether to add a rug plot of the event times to the current
    plot (default=TRUE)}
  \item{var}{specify the variable name or names for the
    exposed/unexposed (names are given as characters)}
  \item{exposed}{function that takes newdata and returns the exposed
    dataset. By default, this increments \code{var}}
  \item{times}{specifies the times. By default, this uses a span of the
                      observed times.}
  \item{\dots}{additional arguments (add to the \code{plot} command)}
