Given a markovchain object and reward values for every state, function calculates expected reward value for a set A of states after n steps.
expectedRewardsBeforeHittingA(markovchain, A, state, rewards, n)the markovchain-class object
set of states for first passage expected reward
initial state
vector depicting rewards coressponding to states
no of steps of the process
returns a expected reward (numerical value) as described above
The function returns the value of expected first passage rewards given rewards coressponding to every state, an initial state and number of steps.
