plot.multivPenal: Plot Method for a multivariate frailty model.

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

Plot Method for a multivariate frailty model.

Description

Plots of estimated baseline survival and hazard functions of a multivariate frailty model (output from an object of class 'multivPenal' for multivariate frailty models ) for each type of event (recurrent, terminal and second recurrent). Confidence intervals are allowed.

Usage

## S3 method for class 'multivPenal'
plot(x, event = "Both", type.plot = "Hazard",
conf.bands = FALSE, pos.legend = "topright", cex.legend = 0.7, ylim, main,
color1="red", color2="blue", colorEnd="green", median=TRUE, Xlab = "Time", 
Ylab = "Hazard function", ...)

Arguments

x	A joint multivariate model, i.e. an object of class multivPenal (output from calling multivPenal function).
event	a character string specifying the type of outcome. Possible value are "Terminal", "Recurrent", "Recurrent2", 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 intervals 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	curve color for recurrent event of type 1 (integer or color name in quotation marks)
color2	curve color for recurrent event of type 2 (integer or color name in quotation marks)
colorEnd	curve color for terminal event (integer or color name in quotation marks)
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 graphical parameters

Value

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