Create a Survival Object for INLA

Description

Create a survival object, to be used as a response variable in a model formula for the inla function for survival models.

Usage

inla.surv(time, event, time2, truncation, subject=NULL)
## S3 method for class 'inla.surv'
plot(x, y, ...)
## S3 method for class 'inla.surv'
print(x, ...)
is.inla.surv(object)
as.inla.surv(object, ...)

Arguments

`time`	For right censored data, this is the follow up time. For interval data, this is the starting time for the interval. For in-interval event, this is the observed time to event.
`event`	The status indicator, 1=observed event, 0=right censored event, 2=left censored event, 3=interval censored event, and 4=observed event in an interval (left, right). Although unusual, the event indicator can be omitted, in which case all subjects are assumed to have an event.
`time2`	Ending time for the interval censured data or an in-interval event.
`truncation`	Left truncation. If missing it is assumed to be 0. The lower limit for event=4.
`subject`	Patient number in multiple event data, not needed otherwise.
`object`	Any `R`-object
`x`	Object to plot or print
`y`	Object to plot (not in use)
`...`	Additional argument

Value

An object of class inla.surv. There are methods for print, plot for inla.surv objects.

is.inla.surv returns TRUE if object inherits from class inla.surv, otherwise FALSE.

as.inla.surv returns an object of class inla.surv
