Generate the factorial run table for decomposition

Creates a data.table with one row per counterfactual combination. Each factor column contains 0 (counterfactual) or 1 (observed), encoding whether that factor is "on" or "off" for that run.

Usage

make_run_table(factors)

Arguments

factors

Character vector of factor names.

Value

A data.table with 2^n rows: run_id (integer), and one column per factor with values 0 or 1.

Examples

make_run_table(c("treatment", "prevention", "demography"))
#>    run_id treatment prevention demography
#>     <int>     <int>      <int>      <int>
#> 1:      1         0          0          0
#> 2:      2         1          0          0
