paths  R Documentation 
For a given multistate model, specified through a transition matrix,
paths
recursively finds all the possible trajectories or paths
through that multistate starting from a specified state. DO NOT USE for
reversible or cyclic multistate models.
paths(trans, start = 1)
trans 
The transition matrix describing the multistate model, see

start 
The starting state for the trajectories 
The function is recursive. It starts in start
, looks at what states
can be visited from start
, and appends the results of the next call
to the current value (matrix). If the transition matrix contains loops, the
function will find infinitely many paths, so do not use paths
for
reversible or cyclic multistate models. A warning is not yet incorporated!
A matrix, each row of which specifies a possible path through the multistate model.
