Generate example SingleCellExperiment object — sce

This function generates a SingleCellExperiment object with 2 batches and 2 datasets. The object contains 300 genes and 600 cells. The counts matrix is generated using the rpois function with different lambda values for the two batches.

sce_example(seed = 42)

Arguments

seed: The seed for the random number generator. Because this function is only used locally, we allow to set a seed within the function.

Value

A SingleCellExperiment object
