transMat: Define transition matrix for multi-state model

Description

Define transition matrices for multi-state model. Specific functions for defining such transition matrices are pre-defined for common multi-state models like the competing risks model and the illness-death model.

Usage

transMat(x, names)
trans.comprisk(K, names)
trans.illdeath(names)

Arguments

x

List of possible transitions; x[[i]] consists of a vector of state numbers reachable from state i

K

The number of competing risks

names

A character vector containing the names of either the competing risks or the states in the multi-state model specified by the competing risks or illness-death model. names should have the same length as the list x (for <

Value

• A transition matrix describing the states and transitions in the multi-state model.

Details

If names is missing, the names "eventfree", "cause1", etcetera are assigned in trans.comprisk, or "healthy", "illness", "death" in trans.illdeath.

Examples

transMat(list(c(2, 3), c(), c(1, 2)),
	names = c("Disease-free", "Death", "Relapsed"))
tmat <- transMat(x = list( c(2, 3), c(1, 3), c() ),
                 names = c("Normal", "Low", "Death"))
tmat
transListn <- list("Normal" = c(2, 3), "Low" = c(1, 3), "Death" = c())
transMat(transListn)
trans.comprisk(3)
trans.comprisk(3,c("c1","c2","c3"))
trans.comprisk(3,c("nothing","c1","c2","c3"))
trans.illdeath()
trans.illdeath(c("nothing","ill","death"))
