R: Add point-wise confidence limits to the graphs of...

confInt {prodlim} | R Documentation

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

### Description

This function is invoked and controlled by `plot.prodlim`.

### Usage

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

### Arguments

`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 `"cuminc"` or `"survival"` passed to summary.prodlim as `surv=ifelse(type=="cuminc",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.

### Details

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

### Value
