Control parameter grouping and names — set

Parameters are grouped by compatible type by default. For example, two lognormal accumulators expose one m, one s, and one t0 parameter unless you ask for specific parameters to be separate. Triggers expose their trigger name directly, and sampled mixtures expose automatic p.<component> parameters.

Usage

set_parameters(spec, separate = NULL, share = NULL, rename = NULL)

Arguments

spec: A race_spec object.
separate: Named list. Each name is a grouped public parameter, and each value is one or more accumulator ids to split from that group. Use TRUE to split every member of a group.
share: Named list mapping a new public name to default public names or internal parameter names that should share one value.
rename: Named character vector mapping current public names to new public names.

Value

The updated race_spec.

Examples

spec <- race_spec() |>
  add_accumulator("go", "lognormal") |>
  add_accumulator("stop", "lognormal") |>
  add_outcome("go", "go") |>
  add_outcome("stop", "stop") |>
  set_parameters(
    separate = list(m = c("go", "stop")),
    rename = c(s = "spread", t0 = "nondecision")
  )

par_names(spec)
#> [1] "go.m"        "spread"      "nondecision" "stop.m"
