frailtypack (version 2.4.1)

plot.jointPenal: Plot Method for a Joint frailty model.

Description

Plots estimated baseline survival and hazard functions of a joint frailty model (output from an object of class 'frailtyPenal' for joint frailty models ) for each type of event (terminal or recurrent). Confidence bands are allowed.

Usage

## S3 method for class 'jointPenal':
plot(x, event = "both", type.plot = "hazard", conf.bands = FALSE,
 pos.legend="topright", cex.legend=0.7, ylim, main, color1, color2, ...)

Arguments

x

A joint model, or more generaly an object of class frailyPenal for Joint frailty model (output from calling frailtyPenal function).

event

a character string specifying the type of curve. Possible value are "terminal", "recurrent", or "both". The default is "both".

type.plot

a character string specifying the type of curve. Possible value are "hazard", or "survival". The default is "hazard". Only the first words are required, e.g "haz", "su"

conf.bands

logical value. Determines whether confidence bands will be plotted. The default is to do so.

pos.legend

The location of the legend can be specified by setting this argument to a single keyword from the list '"bottomright"', '"bottom"', '"bottomleft"', '"left"', '"topleft"', '"top"', '"topright"', '"right"' and '"center"'. The default is '"topright"'

cex.legend

character expansion factor *relative* to current 'par("cex")'. Default is 0.7

ylim

y-axis limits

main

plot title

color1

color of the curve (integer or color name in quotation marks)

color2

color of the second curve if both recurrent and terminal events are plotted

...

other unused arguments

Value

• Print a plot of the baseline survival or hazard functions for each type of event or both with the confidence bands or not (conf.bands argument)
