Define the external parameter names for a model — set

`set_parameters()` lets you rename parameters and share them across accumulators using one simple mapping. Each list name is the external parameter name users will supply; each value is one or more internal model parameter names such as `go.m` or `stop.t0`.

Usage

set_parameters(spec, parameters)

Arguments

spec: A `race_spec` object.
parameters: A named list mapping external names to one or more model parameter names.

Value

The updated `race_spec`.

Details

Any parameters not mentioned in `parameters` keep their default names.

Examples

spec <- race_spec() |>
  add_accumulator("go", "lognormal") |>
  add_accumulator("stop", "lognormal") |>
  add_outcome("go", "go") |>
  add_outcome("stop", "stop") |>
  set_parameters(list(
    drift = c("go.m", "stop.m"),
    spread = c("go.s", "stop.s"),
    onset = "go.t0"
  ))

sampled_pars(spec)
#> [1] "drift"   "spread"  "go.q"    "onset"   "stop.q"  "stop.t0"
