tree |
A tree object of class |
rate.mat |
A reversible continuous-time Markov chain (CTMC) rate matrix. |
label.mat |
A 0-1 matrix of the same size as |
edge.set |
An integer vector of branch indices specifying the branch set over which the posterior moments will be calculated. |
root.dist |
A numeric vector defining the root distribution of the evolutionary process on the tree. If this process starts at stationarity (as is commonly assumed), then the root distribution is equal to the CTMC stationary distribution. |
scale |
A logical indicating whether to scale the time dimension. If
|
states |
A character or integer vector denoting the CTMC state space.
Defaults to the set of DNA nucleotides |
seq.data |
A character or integer matrix representing the observed
sequence alignment with rows (columns) that correspond to the sequences
(sites) under study. All elements of |
