Fixed Transition Probability

[Henrywcj]

Hi there,

I am trying to set the transition matrix to be fixed, like:
constraint.spec = list(fixed=list(P_1_1 =0)) inside CreateSpec()
It works with the CreateSpec() but raise error for both FitML() and FitMCMC(). The error is “Wrong name in fixed.pars: “

Any help would be appreciated!
