MSBVAR Package

dear sirs or madam,

As I'm interested to search about the monetary transmission channel in our
country by MSVAR model, I would be grateful if you help me and tell me how
can I run MSVAR in R or send me the related code to run this model .
Actually, I'm new user of R and I don't know how to run Markov Switching
Var Model in R.

Thank you very much in advance for your help.

Best Regards,
Ahmad Arabian
