markovchain (version 0.6.9)

markovchain-package:

Description

The package contains classes and method to create and manage (plot, print, export for example) discrete time Markov chains (DTMC). In addition it provide functions to perform statistical (fitting and drawing random variates) and probabilistic (analysis of DTMC proprieties) analysis.

 mcA<-new("markovchain", transitionMatrix=matrix(c(0.7,0.3,0.1,0.9),byrow=TRUE,
 nrow=2, dimnames=list(statesNames,statesNames)))

statesNames=c("a","b","c")

          matrix(c(0.2,0.5,0.3,
                   0,1,0,
