Graphical comparing of cumulative hazards

Description

Comparison of the cumulative hazards functions for a semi-parametric and parametric models.

Usage

plotHaz(
  sp,
  pp,
  interval,
  main = NULL,
  xlab = "Time",
  ylab = "Cum. hazards",
  leglab,
  col = c("blue", "red"),
  lty = 1:2,
  ylim,
  log = "",
  printLegend = TRUE
)

Arguments

sp	An object of type "coxreg" or "phreg", typically output from coxreg or phreg.
pp	An object of type "coxreg" or "phreg", typically output from coxreg or phreg.
interval	Time interval for the plot, if missing, calculated from sp.
main	Header for the plot. Default is distribution and "cumulative hazard function"
xlab	Label on x axis (default "Time")
ylab	Label on y axis (default "Cum. Hazards")
leglab	Labels in legend.
col	Line colors. should be NULL (black lines) or of length 2
lty	line types.
ylim	Y limits for the plot.
log	Argument sent to plot, defaults to "".
printLegend	Should a legend be printed? Default is TRUE.

Details

For the moment only a graphical comparison. The arguments sp and pp may be swapped.

Value

No return value.
