Project an Opal object and retain the result

Runs project_dynamics() and stores the result, settings, and the identity of its source fit or posterior. Inputs for future recruitment, selectivity, and catch remain explicit scientific choices. Updating the model or replacing the source fit/posterior clears stored projections.

Usage

opal_project(x, uncertainty = NULL, name = "projection", seed = NULL, ...)

Arguments

x

A fitted or sampled opal_obj.

uncertainty

Either "mvn" or "mcmc"; required when a posterior exists.

name

Name of the result in x$derived.

seed

Optional random seed, restored after the projection.

...

Arguments passed to project_dynamics(), including future inputs.

Value

An updated opal_obj with a stored projection.

Details

Read the stored output from x$derived[[name]]$result; settings records the future inputs and seed, and identity records the source result. Set a seed separately before stochastic recruitment or selectivity helpers; the seed argument here controls the dynamics projection only. For a complete worked example, see vignette("projections").
