Examples

data(survey, package = "MASS")
columns <- c("Sex", "Age", "Smoke")
nas <- c(137, 70) # Omit rows with NA to avoid warnings in design
index <- design(pheno = survey[-nas, columns], size_subset = 70,
                iterations = 10)
batches <- inspect(index, survey[-nas, columns])
distribution(batches, "Sex")
#> [1] TRUE
distribution(batches, "Smoke")
