Whenever a Gibbs sampler is employed, it is always a good idea to ensure that parameter samples are being obtained correctly - that burn-in has been achieved, and that appropriate mixing is taking place, for example. `as.mcmc.blca.gibbs`

converts an object of class `blca`

to that of `mcmc`

to avail of the diagnostic checks available in other R packages, particularly those in the **coda** package.

An *N \times G*(M+1)* matrix of class `mcmc`

, where N is the number of data points, M the number of columns and G the number of classes. The first G columns (labelled ClassProb 1 , ..., ClassProb G) are class membership probability samples, the next G*M columns (labelled ItemProb 1 1 , ItemProb 1 2, ..., ItemProb G 1, ..., ItemProb G M) are item response probability samples.

This function replaces the function `mcmc2blca`

, which appeared in the original version of the package, and which is retained as an internal function for backwards compatibility reasons.
