mc_match: Match Monte Carlo Nodes

In mcmodule: Modular Monte Carlo Risk Analysis

Match Monte Carlo Nodes

Description

Matches two mcnodes by:

1. Group matching - Align nodes with same scenarios but different group order

2. Scenario matching - Align nodes with same groups but different scenarios

3. Null matching - Add missing groups across different scenarios

Usage

mc_match(mcmodule, mc_name_x, mc_name_y, keys_names = NULL)

Arguments

mcmodule	Monte Carlo module
mc_name_x	First node name
mc_name_y	Second node name
keys_names	Names of key columns

Value

List containing matched nodes and combined keys (keys_xy)

Examples

test_module <- list(
  node_list = list(
    node_x = list(
      mcnode = mcstoc(runif,
        min = mcdata(c(1, 2, 3), type = "0", nvariates = 3),
        max = mcdata(c(2, 3, 4), type = "0", nvariates = 3),
        nvariates = 3
      ),
      data_name = "data_x",
      keys = c("category")
    ),
    node_y = list(
      mcnode = mcstoc(runif,
        min = mcdata(c(5, 6, 7), type = "0", nvariates = 3),
        max = mcdata(c(6, 7, 8), type = "0", nvariates = 3),
        nvariates = 3
      ),
      data_name = "data_y",
      keys = c("category")
    )
  ),
  data = list(
    data_x = data.frame(
      category = c("A", "B", "C"),
      scenario_id = c("0", "0", "0")
    ),
    data_y = data.frame(
      category = c("B", "B", "B"),
      scenario_id = c("0", "1", "2")
    )
  )
)

result <- mc_match(test_module, "node_x", "node_y")
