survTP: Create a survTP object

Description

Creates a ‘survTP’ object, usually used as input to other functions.

Usage

survTP(time1, event1, Stime, event, ...)
	is.survTP(x)

Arguments

time1

Time of the transition into state 2, state 3 or censoring time.

event1

Indicator of transition into state 2 or state 3; 0 if the transition time is censored and 1 otherwise.

Stime

The total time of the process.

event

Censoring indicator of the total time of the process; 0 if the total time is censored and 1 otherwise.

…

Any number of covariates can be specified.

x

Any R object.

Value

An object of class ‘survTP’.

‘survTP’ objects are implemented as a single element list

data

a data.frame with time1, event1, Stime, event and covariates as columns.

In the case of is.survTP, a logical value TRUE if x inherits from class survTP, otherwise FALSE.

Examples

# NOT RUN {
data(bladderTP)
bladderTP_obj <- with(bladderTP, survTP(time1, event1, Stime, event))
#or
bladderTP_obj <- survTP(bladderTP$time1, bladderTP$event1, bladderTP$Stime,
bladderTP$event)
data(heartTP)
heartTP_obj <- with(heartTP, survTP(time1, event1, Stime, event, age=age))
#or
heartTP_obj <- survTP(heartTP$time1, heartTP$event1, heartTP$Stime,
heartTP$event, age=heartTP$age)
# }
