Add fitted flexible survival curves to a plot

Source: R/plot.flexsurvreg.R
lines.flexsurvreg.Rd

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

Usage

# S3 method for 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).
