plot.intensity {event}

Plot Intensity Functions

Description

Plot the empirical intensity curve for given times between events.

Usage

## S3 method for class 'intensity'
plot(x, ...)
## Default S3 method:
plot.intensity(x, censor=1, group=1, colour=TRUE, mix=1,
	ylim=c(0,1), ylab="p", xlab="Time",
	main="Empirical Hazard Function(s)", ...)

Arguments

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.

x

An object produced by km for plot.intensity; for plot.intensity.default it is times (Vector of times to events or a list of vectors of such times for different individuals.) These changes were made for S3 methods compatability.
