set_levels {SimEngine}

Set simulation levels

Description

Set one or more simulation levels, which are things that vary between simulation replicates.

Usage

set_levels(sim, ..., .keep = NA)

Arguments

sim

A simulation object of class sim_obj, usually created by new_sim

...

One or more key-value pairs representing simulation levels. Each value can either be a vector (for simple levels) or a list of lists (for more complex levels). See examples.

.keep

An integer vector of level_id values specifying which level combinations to keep; see the Advanced Functionality documentation.

Value

The original simulation object with the old set of levels replaced with the new set

Examples

# Basic simulation levels are numeric or character vectors
sim <- new_sim()
sim %<>% set_levels(
  n = c(10, 100, 1000),
  est = c("M", "V")
)

# Complex simulation levels can be set using named lists of lists
sim <- new_sim()
sim %<>% set_levels(
  n = c(10, 100, 1000),
  distribution = list(
    "Beta 1" = list(type="Beta", params=c(0.3, 0.7)),
    "Beta 2" = list(type="Beta", params=c(1.5, 0.4)),
    "Normal" = list(type="Normal", params=c(3.0, 0.2))
  )
)
