confInt

Add point-wise confidence limits to the graphs of Kaplan-Meier and Aalen-Johansen estimates.

This function is invoked and controlled by plot.prodlim.

confInt(x, times, newdata, type, citype, cause, col, lty, lwd,
  density = 55, ...)

`x`	an object of class ‘prodlim’ as returned by the `prodlim` function.
`times`	where to compute point-wise confidence limits
`newdata`	see `plot.prodlim`
`type`	Either `"risk"` (AKA `"cuminc"`) or `"survival"` passed to summary.prodlim as `surv=ifelse(type=="risk",FALSE,TRUE)`.
`citype`	If `"shadow"` then confidence limits are drawn as colored shadows. Otherwise, dotted lines are used to show the upper and lower confidence limits.
`cause`	see `plot.prodlim`
`col`	the colour of the lines.
`lty`	the line type of the lines.
`lwd`	the line thickness of the lines.
`density`	For `citype="shadow"`, the density of the shade. Default is 55 percent.
`...`	Further arguments that are passed to the function `segments` if `type=="bars"` and to `lines` else.

This function should not be called directly. The arguments can be specified as Confint.arg in the call to plot.prodlim.
