Examples

data(iris)

# Create metadata: Data frame with sample names and a group factor
metadata <- data.frame(sample_id = paste0("sample_", 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)
