c.mcmc: Combine an mcmc object
In thlytras/FluHMM: Hidden Markov Model for influenza sentinel surveillance

This method combines ‘mcmc’ objects into a single ‘mcmc’ object. Objects must have come from the same model and have the same variable names.

1 2	## S3 method for class 'mcmc' c(..., start = NA, thin = NA)

`...`	‘mcmc’ objects to be concatenated
`start`	Iteration number of first observation in the chain, for the resulting object. If `NA`, the first iteration number of the first ‘mcmc’ object is used.
`thin`	Thinning interval between consecutive observations, for the resulting object. If `NA`, the thinning interval of the first ‘mcmc’ object is used.
