get.mig.prediction {bayesMig}

Access Prediction Object

Description

Function get.mig.prediction retrieves results of a prediction and creates an object of class bayesMig.prediction. Function has.mig.prediction checks an existence of such results.

Usage

get.mig.prediction(mcmc = NULL, sim.dir = NULL, mcmc.dir = NULL)

has.mig.prediction(mcmc = NULL, sim.dir = NULL)

Arguments

mcmc

Object of class bayesMig.mcmc.set used to make the prediction. If it is NULL, the prediction is loaded from directory given by sim.dir.

sim.dir

Directory where the prediction is stored.

mcmc.dir

Optional argument to be used only in a special case when the mcmc object contained in the prediction object was estimated in different directory than in the one to which it points to (for example due to moving or renaming the original directory). The argument causes that the mcmc is redirected to the given directory. It can be set to NA if no loading of the mcmc object is desired.

Details

If mcmc is not NULL, the search directory is set to mcmc$meta$output.dir. This approach assumes that the prediction was stored in the same directory as the MCMC simulation, i.e. the output.dir argument of the mig.predict function was set to NULL. If it is not the case, the argument mcmc.dir should be used.

Value

Function get.mig.prediction returns an object of class bayesMig.prediction.

Function has.mig.prediction returns a logical indicating if a prediction exists.
