importExampleData {singleCellTK} | R Documentation

## Retrieve example datasets

### Description

Retrieves published example datasets stored in SingleCellExperiment using the scRNAseq and TENxPBMCData packages. See 'Details' for a list of available datasets.

### Usage

    importExampleData(dataset, class = c("Matrix", "matrix"), delayedArray = FALSE)

### Arguments

`dataset` | Character. Name of the dataset to retrieve.
`class` | Character. The class of the expression matrix stored in the SCE object. Can be one of `"Matrix"` or `"matrix"`. `"Matrix"` will store the data as a sparse matrix from package Matrix while `"matrix"` will store the data in a standard matrix. Default `"Matrix"`.
`delayedArray` | Boolean. Whether to read the expression matrix as DelayedArray object or not. Default `FALSE`.
