Methods (by generic)

• as.list: Convert to list class

• numdp: Get number of DPs

• numconparam: Get number of concentration parameters

• base: Get base distribution

• conparam: Get list of concentration parameters

• dp: Get list of DP nodes

• dpstate: Get state of every DP

• ppindex: Get parent process index of every DP

• cpindex: Get concentration parameter index of every DP

• numcateg: Get number of data categories

• base_params: Get parameters of the base Dirichlet distribution (like psuedocounts across categories).

• activating_seed: Get seed used to initialse clustering

• pseudoDP: Get index of frozen pseudo-data DP nodes for prior info (only if initialised via hdp_prior_init)
