Get likelihood snapshots

Get the last snapshots from a likelihood.

Usage

dust_likelihood_last_snapshots(obj, select_random_particle = FALSE)

Arguments

obj

A dust_filter object, created by dust_filter_create or a dust_unfilter object created by dust_unfilter_create

select_random_particle

Logical, indicating if we should return a history for one randomly selected particle (rather than the entire set of trajectories over all particles). If this is TRUE, the particle will be selected independently for each group, if the object is grouped. This option is intended to help select a representative trajectory during an MCMC. When TRUE, we drop the particle dimension of the return value.

Value

An array. If ungrouped this will have dimensions state x particle x time (where time here is along your snapshot times), and if grouped then state x particle x group x time. If select_random_particle = TRUE, the second (particle) dimension will be dropped.
