Plot method for coxreg objects — plot.coxreg • eha

A plot of a baseline function of a coxreg fit is produced, one curve for each stratum. A wrapper for plot.survfit in survival.

# S3 method for coxreg
plot(
  x,
  fn = c("cum", "surv", "log", "loglog"),
  conf.int = FALSE,
  fig = TRUE,
  xlim = NULL,
  ylim = NULL,
  main = NULL,
  xlab = "Duration",
  ylab = "",
  col = 1,
  lty = 1,
  printLegend = TRUE,
  ...
)

Arguments

x	A `coxreg` object
fn	What should be plotted? Default is "cumhaz", and the other choices are "surv", "log", and "loglog".
conf.int	logical or a value like 0.95 (default for one curve).
fig	logical. If `TRUE` the plot is actually drawn, otherwise only the coordinates of the curve(s) are returned.
xlim	Start and end of the x axis.
ylim	Start and end of the y axis.
main	A headline for the plot
xlab	Label on the x axis.
ylab	Label on the y axis.
col	Color of the curves. Defaults to 'black'.
lty	Line type(s).
printLegend	Either a logical or a text string; if `TRUE`, a legend is printed at a default place, if `FALSE`, no legend is printed. Otherwise, if a text string, it should be one of "bottomleft", "bottomright", "topleft", etc., see `legend` for all possible choices.
...	Other parameters to pass to the plot.

Value

An object of class hazdata containing the coordinates of the curve(s).
