lines.flexsurvreg: Add fitted flexible survival curves to a plot
In flexsurv: Flexible parametric survival models

Description Usage Arguments Author(s) See Also

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

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

## S3 method for class 'flexsurvreg'
lines(x, 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, ...)

`x`	Output from `flexsurvreg`, representing a fitted survival model object.
`X`	Matrix of covariate values to produce fitted curves for, 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.
