plot.idm: Plot method for an illness-death model.

Description

Plot estimated baseline transition intensities from an object of class idmWeib or idmPl. Confidence bands are allowed.

Usage

## S3 method for class 'idm':
plot(x, conf.bands=FALSE, ylim,
 pos.legend = "topleft", main, transition, ...)

Arguments

x

a idmWeib class object or a idmPl class object (output from calling idm function).

conf.bands

logical value. Determines whether confidence bands will be plotted. The default is FALSE.

ylim

vector containing the y limites (min, max) of the plot. The default is the min and the max of all the values of the three transition intensities

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 "topleft"

main

title of plot

transition

a vector of the transitions to plotted on separate graphs. Possible value are "01","02" and "12". The default is a plot of the 3 intensities on the same graph.

...

other graphical parameters.

Value

• Print a plot of the baseline transition intensities of an illness-death model.

Examples

# Weibull illness deaths model 
data(Dem15_h_3)
d <- Dem15_h_3
names(d) <- c("dementia","mort","entry","L","R","time","cep")

fit.weib <- idm(formula02=Hist(time,event=mort,entry=entry)~cep,
formula01=Hist(time=list(L,R),event=dementia)~cep,data=d) 

# no confidence bands
plot(fit.weib)

# confidence bands for transition 0 --> 1
plot(fit.weib,conf.bands=TRUE,transition="01")
