data(iris)

# Create metadata: Data frame with sample names and a group factor
metadata <- data.frame(ID = 1:150, Group = iris$Species)

# Create features: `p` column data frame with features
features <- iris[, 1:4]

# Create a `SummarizedExperiment` object with `POMA`
object <- PomaCreateObject(metadata = metadata, features = features)
