markovchain (version 0.9.5)

ctmc-class: Continuous time Markov Chains class

Description

The S4 class that describes ctmc (continuous time Markov chain) objects.

Arguments

states

Name of the states. Must be the same of colnames and rownames of the generator matrix

byrow

TRUE or FALSE. Indicates whether the given matrix is stochastic by rows or by columns

generator

Square generator matrix

name

Optional character name of the Markov chain

Methods

dim

signature(x = "ctmc"): method to get the size

initialize

signature(.Object = "ctmc"): initialize method

states

signature(object = "ctmc"): states method.

steadyStates

signature(object = "ctmc"): method to get the steady state vector.

plot

signature(x = "ctmc", y = "missing"): plot method for ctmc objects
