Plots output from an AFT regression

Source: R/plot.aftreg.R

Just a simple plot of the hazard (cumulative hazard, density, survival) functions for each stratum.

# S3 method for aftreg
plot(
  x,
  fn = c("haz", "cum", "den", "sur"),
  main = NULL,
  xlim = NULL,
  ylim = NULL,
  xlab = "Duration",
  ylab = "",
  col,
  lty,
  printLegend = TRUE,
  new.data = x$means,
  ...
)

Arguments

x

A aftreg object
fn

Which functions shoud be plotted! Default is all. They will scroll by, so you have to take care of explicitly 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

y label
col

Colors?
lty

Line types?
printLegend

Should legend be printed? Default is yes.
new.data

At which covariate values?
...

Extra parameters passed to 'plot'

Value

No return value.

Details

The plot is drawn at the mean values of the covariates, by default.

Examples


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