create_trans_dt(trans_mat)

Arguments

trans_mat

A transition matrix in the format from the mstate package. See IndivCtstmTrans.

Value

Returns a data.table in tidy format with three columns:

transition_id

Health state transition ID.

from

The starting health state.

to

The health state that will be transitions to.

Examples

tmat <- rbind(c(NA, 1, 2), c(NA, NA, 3), c(NA, NA, NA)) create_trans_dt(tmat)
#> transition_id from to #> 1: 1 1 2 #> 2: 2 1 3 #> 3: 3 2 3
