get_draws: Get MCMC trace draws.

In bayfoxr: Global Bayesian Foraminifera Core Top Calibration

Description

Get MCMC trace draws.

Usage

get_draws(foram = NULL, seasonal_seatemp = FALSE)

Arguments

foram	Optional. String or NULL. String indicating the foram species/subspecies to infer for hierarchical models. String must be one of "G. bulloides", "G. ruber white", "G. ruber pink", "G. sacculifer", "N. incompta", or "N. pachyderma sinistral". NULL indicates that a pooled model is desired.
seasonal_seatemp	Optional boolean indicating whether to use the seasonal sea-surface temperature calibrations. Default is FALSE, i.e. using annual SST calibrations.

Details

Four calibration models are available: an "annual pooled" model, a "seasonal pooled" model, an "annual hierarchical" model, and a "seasonal hierarchical" model. This function uses magic to determine which "pooled annual" model is used. Which is the simplest case with potential use for Deep Time reconstructions of nonexant foram species. Giving a valid string for foram will use a hierarchical model, which has foram-specific variability in calibration model parameters. Passing TRUE for seasonal_seatemp will use a model trained on season sea-surface temperatures. See reference paper for further details.

Value

Data frame with columns "alpha", "beta", "tau". Which are equal-length vectors of model parameter draws.
