time |
For right censored data, this is the follow up time. For interval data, this is the starting time for the interval. |
event |
The status indicator, 1=observed event, 0=right censored event, 2=left censored event, 3=interval censored event. 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. |
truncation |
Left truncation. If missing it is assumed to be 0. |
subject |
Patient number in multiple event data, not needed otherwise. |
object |
Any |
x |
Object to plot or print |
y |
Object to plot (not in use) |
... |
Additional argument |
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
