R: Add fitted flexible survival curves to a plot

lines.flexsurvreg {flexsurv} | R Documentation

## Add fitted flexible survival curves to a plot

### Description

Add fitted survival (or hazard or cumulative hazard) curves from a `flexsurvreg` model fit to an existing plot.

### Usage

    ## S3 method for class 'flexsurvreg'
    lines(
      x,
      newdata = NULL,
      X = NULL,
      type = "survival",
      t = NULL,
      est = TRUE,
      ci = NULL,
      B = 1000,
      cl = 0.95,
      col = "red",
      lty = 1,
      lwd = 2,
      col.ci = NULL,
      lty.ci = 2,
      lwd.ci = 1,
      ...
    )

### Arguments

`x` | Output from `flexsurvreg`, representing a fitted survival model object.
`newdata` | Covariate values to produce fitted curves for, as a data frame, as described in `plot.flexsurvreg`.
`X` | Covariate values to produce fitted curves for, as a matrix, as described in `plot.flexsurvreg`.
`type` | `"survival"` for survival, `"cumhaz"` for cumulative hazard, or `"hazard"` for hazard, as in `plot.flexsurvreg`.
`t` | Vector of times to plot fitted values for.
`est` | Plot fitted curves (`TRUE` or `FALSE`.)
`ci` | Plot confidence intervals for fitted curves.
`B` | Number of simulations controlling accuracy of confidence intervals, as used in `summary`.
`cl` | Width of confidence intervals, by default 0.95 for 95% intervals.
`col` | Colour of the fitted curve(s).
`lty` | Line type of the fitted curve(s).
`lwd` | Line width of the fitted curve(s).
`col.ci` | Colour of the confidence limits, defaulting to the same as for the fitted curve.
`lty.ci` | Line type of the confidence limits.
`lwd.ci` | Line width of the confidence limits, defaulting to the same as for the fitted curve.
`...` | Other arguments to be passed to the generic `plot` and `lines` functions.

### Details

Equivalent to `plot.flexsurvreg(...,add=TRUE)`.
