[R] A question about MIX package

[Li, Jia]

Hello all,
 
When I used commands "ecm.mix and dabipf.mix" to do a simulation (sample size is small 100), I got an error : Steps of ECM, missing value where True/False needed.
 
I've checked the menu, and the option "prior" of ecm.mix said that if structural zeros appear in the table, hyperparameters for those cells should be set to NA. However, it didn't say how to do that in the command. I am wondering if someone knows how to fix this.
 
I appreciate your help,
 
Jia
