get_transition_from_path {triversity} | R Documentation |
get_transition_from_path
computes the transition matrix of a random walk following a
path
between the different levels of the input tripartite
graph.
get_transition_from_path(tripartite, path)
tripartite |
A tripartite graph obtained by calling the |
path |
A vector of integers in { |
Note that the tripartite graph structure implemented in this package
stores in memory any computed transition matrix to avoid redundant computation
in the future. Hence, the first execution of get_transition_from_path
, or of
any other function that builds on it, can be much slower than latter calls.
The transition matrices are stored within a data.tree
in the input tripartite
variable (see tripartite$transitions
).
A matrix of floats in [0
,1
], with all lines summing to 1
,
giving the transition matrix of the random walk following the input path
.
