Assemble and Validate min_pmix Functions for a Simulation Scenario

Collects one or more min_pmix functions into a validated, named collection - the single entry point through which ssd_define_scenario() takes min_pmix input. Each entry must be a single-argument function (it inputs the number of rows of data and returns a proportion between 0 and 0.5); a name-string is not accepted, so the constructor performs no string-to-function resolution.

Usage

ssd_pmix(...)

Arguments

...

One or more single-argument functions, optionally named.

Value

An ssdsims_pmix object: a named list of validated single-argument functions.

Details

Names are taken from the argument names where supplied, otherwise derived from the argument expression by symbol capture (e.g. ssdtools::ssd_min_pmix becomes "ssd_min_pmix"), mirroring ssd_scenario_data(). Names must be unique across the collection. The name - not the function value - is what the task path hashes; the functions ride on the scenario for execution, isolated by name via scenario_min_pmix().

ssd_define_scenario(), scenario_min_pmix().

Examples

ssd_pmix(ssdtools::ssd_min_pmix)
#> <ssdsims_pmix>
#>   ssd_min_pmix: <fn>
ssd_pmix(ssd_min_pmix = ssdtools::ssd_min_pmix, strict = function(n) 0.1)
#> <ssdsims_pmix>
#>   ssd_min_pmix: <fn>
#>   strict: <fn>
