Description

Create a transition matrix describing patient transitions between health states.

Usage

create_trans_mat(object)

Arguments

object

A model_structure object.

Value

A transition matrix of the same format as in the mstate package.

Examples

txseq1 <- txseq(first = "erlotinib",
               second = c("osimertinib", "PBDC"),
               second_plus = c("PBDC + bevacizumab", "PBDC + bevacizumab"))
txseq2 <- txseq(first = "gefitinib",
               second = c("osimertinib", "PBDC"),
               second_plus = c("PBDC + bevacizumab", "PBDC + bevacizumab")) 
txseqs <- txseq_list(seq1 = txseq1, seq2 = txseq2) 

struct1 <- model_structure(txseqs, n_states = "four")
create_trans_mat(struct1)
 
struct2 <- model_structure(txseqs, n_states = "three")
create_trans_mat(struct2)
 
txseqs <- txseq_list(seq1 = txseq1, seq2 = txseq2, 
                     start_line = "second", mutation = "positive")
struct3 <- model_structure(txseqs, n_states = "three")
create_trans_mat(struct3)
