Reveal any messages about your models during a multiverse analysis

Usage

reveal_model_messages(.multi, .unpack_specs = "no")

Arguments

.multi: a multiverse list-column tibble produced by run_multiverse.
.unpack_specs: character, options are "no", "wide", or "long". "no" (default) keeps specifications in a list column, wide unnests specifications with each specification category as a column. "long" unnests specifications and stacks them into long format, which stacks specifications into a decision_set and alternatives columns. This is mainly useful for plotting.

Value

the unnested model messages captured during analysis.
