Plot Intensity Functions

Description

Plot the empirical intensity curve for given times between events.

Usage

plot.intensity(z, ...)
plot.intensity.default(times, censor=1, group=1, colour=TRUE, mix=1,
        ylim=c(0,1), ylab="p", xlab="Time",
        main="Empirical Intensity Function(s)")

Arguments

times Vector of times to events or a list of vectors of such times for different individuals.
censor Vector of censoring indicators corresponding to the vector of times or to the last time in each vector of a list.
group Vector indicating to which group each individual belongs.
colour Use a different colour for each curve.
