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

In frailtypack: Shared, Joint (Generalized) Frailty Models; Surrogate Endpoints

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 'JointPenal' 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, color = 2, median=TRUE,
Xlab = "Time", Ylab = "Hazard function", ...)

Arguments

x	A joint model, i.e. an object of class frailtyPenal 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 letters 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
color	curve color (integer)
median	Logical value. Determines whether survival median will be plotted. Default is TRUE.
Xlab	Label of x-axis. Default is '"Time"'
Ylab	Label of y-axis. Default is '"Hazard function"'
...	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)
