lines.flexsurvreg

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).
