SeedMaker

R-CMD-check test-coverage lint

{SeedMaker} is a mechanism for easily generating and organizing a collection of seeds from a single seed, which may be subsequently used to ensure reproducibility in processes/pipelines that utilize multiple random components (e.g., trial simulation).

Installation

Install the released version of {SeedMaker} from CRAN:

install.packages("SeedMaker")

Or install the development version of {SeedMaker} from GitHub with:

# install.packages("remotes")
remotes::install_github("hdhshowalter/SeedMaker")

Examples

The following calls are representative of the most common ways to engage seed_maker():

library(SeedMaker)

#simple call
seed_maker(
  seed = 1234,
  level_names = "sim",
  n_per_level = 5
)
