plot.logrank: Plots of hazdata objects.

Description

Baseline hazards estimates.

Usage

# S3 method for logrank
plot(
  x,
  fn = c("cum", "surv", "log", "loglog"),
  xlim = NULL,
  ylim = NULL,
  main = NULL,
  xlab = "",
  ylab = "",
  col = "black",
  lty = 1,
  printLegend = TRUE,
  ...
)

Arguments

A logrank object, typically the 'hazards' element in the output from link{logrank}.

Which type of plot? Allowed values are "cum" (or "cumhaz"), "surv" (or "sur"), "log", or "loglog". The last two plots the cumulative hazards on a log (y) scale or a log-log (xy) scale, respectively.

xlim

Horizontal plot limits. If NULL, calculated by the function.

ylim

Vertical plot limits. If NULL, set to c(0, 1) for a plot of the survival function.

main

A heading for the plot.

xlab

Label on the x axis.

ylab

Label on the y-axis.

col

Color of the lines. May be a vector of length equal to No. of strata.

lty

Line type(s). May be a vector of length equal to No. of strata.

printLegend

Logical or character; should a legend be produced? Defaults to TRUE. If character, it should be one of bottomleft, bottomright, etc, see legend.

...

Anything that plot.default likes...

Value

A list where the elements are two-column matrices, one for each stratum in the model. The first column contains risktimes, and the second the y coordinates for the requested curve(s).

Details

It is also possible to have as first argument an object of type "coxreg", given that it contains a component of type "hazdata".
