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

Plot Method for a Weibull Illness-Death model with optional shared frailty between transitions.

Description

Plots estimated baseline survival and hazard functions from an object of class 'frailtyIllnessDeath'. Confidence bands are allowed.

Usage

## S3 method for class 'frailtyIllnessDeath'
plot(x, type.plot = "Baseline hazard", transition,
   conf.bands=TRUE, pos.legend = "topright", cex.legend=0.7, lwd=c(1,1,1), 
   color=2, median=TRUE, Xlab = "Time", Ylab= "Baseline hazard function",...)

Arguments

x	A Weibull Illness-Death model, i.e. an IllnessDeath class object (output from calling IllnessDeath function).
type.plot	a character string specifying the type of curve. Possible value are "Baseline hazard", or "Baseline survival". The default is "Baseline hazard". Only the first letters are required, e.g "Haz", "Su".
transition	Argument to specify if only the plot of one of the three transitions is wanted. If not specified, the plots for all transitions are displayed. Possible values are "01", "02" or "12".
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.
lwd	A vector of length 3 of positive values to specify the line width of the plots and their confidence bands. If no confidence bands are plotted, the last two elements of the vector are ignored. Default is (1,1,1).
color	color of the curve (integer).
median	Logical value. Determines whether median survival time will be plotted. Default is TRUE.
Xlab	Label of x-axis. Default is '"Time"'.
Ylab	Label of y-axis. Default is '"Baseline hazard function"'.
...	other unused arguments

Value

Print a plot of a Weibull Illness-Death model with optional shared frailty between transitions.

    #-- No confidence bands
    plot(ModIllnessDeath_SemiMarkov_LeftTrunc, conf.bands = FALSE)
