plot.mixpch {nph}

Plot mixpch Objects

Description

Plots survival and other functions stored in mixpch objects versus time.

Usage

## S3 method for class 'mixpch'
plot(
  x,
  fun = c("S", "F", "haz", "cumhaz"),
  add = FALSE,
  ylab = fun,
  xlab = "Time",
  ...
)

Arguments

x

an object of class mixpch.

fun

character string in c("S","F","haz","cumhaz") indicating which function to plot. Select "S" for the survival function, "F" for the distribution functin, "haz" for the hazard function or "cumhaz" for the cumulative hazard function.

add

logical, indicates if the drawing should be added to an existing plot.

ylab

label of the y-axis

xlab

label of the x-axis

...

further arguments passed to the plotting functions
