Description

Just a simple plot of the hazard functions for each stratum.

Usage

plot.phreg(x, fn = c("haz", "cum", "den", "sur"), main = NULL,
xlim = NULL, ylim = NULL, xlab = "Duration", ylab = "",
new.data = x$means, ...)

Arguments

x

A phreg object

fn

Which functions shoud be plotted! Default is all. They will scroll by, so you have to take care explicitely what you want to be produced. See, eg, par(mfrow = ...)

main

Header for the plot

xlim

x limits

ylim

y limits

xlab

x label

ylab

Extra parameters passed to 'plot'

Examples

y <- rllogis(40, shape = 1, scale = 1)
x <- rep(c(1,1,2,2), 10)
fit <- phreg(Surv(y, rep(1, 40)) ~ x, dist = "loglogistic")
plot(fit)
