mockData: Mock data for examples

In SingleR: Reference-Based Single-Cell RNA-Seq Annotation

Description

Make up some test and reference data for the various examples in the SingleR package.

Usage

.mockRefData(ngroups = 5, nreps = 4, ngenes = 1000, prop = 0.5)

.mockTestData(mock.ref, ncells = 100)

Arguments

ngroups	Integer scalar specifying the number of groups.
nreps	Integer scalar specifying the number of replicates per group.
ngenes	Integer scalar specifying the number of genes in the dataset.
prop	Numeric scalar specifying the proportion of genes that are DE between groups.
mock.ref	A SummarizedExperiment object produced by .mockRefData.
ncells	Integer scalar specifying the number of cells to simulate.

Details

This functions are simply provided to simulate some data in the Examples of the documentation. The simulations are very simple and should not be used for performance comparisons.

Value

Both functions return a SummarizedExperiment object containing simulated counts in the counts assay, with the group assignment of each sample in the "label" field of the colData.
