Examples

# Simulate the Jukes-Cantor model of nucleotide replacement 
K <- 4
PJK <- matrix(1/3, nrow = K, ncol = K) - diag(rep(1/3, K))
lambda_PJK <- c(1, 1, 1, 1)
d_JK <- generate_Markov(n = 10, K = K, P = PJK, lambda = lambda_PJK, Tmax = 10)

# cut at Tmax = 8
d_JK2 <- cut_data(d_JK, Tmax = 8)

# compute time spent by each id in each state
timeSpent <- compute_time_spent(d_JK2)
