hypoData {TCC} | R Documentation

## A simulation dataset for comparing two-group tag count data, focusing on RNA-seq

### Description

A simulation dataset, consisting of 1,000 rows (or genes) and 6 columns (or independent biological samples).

### Usage

    data(hypoData)

### Format

`hypoData` is a matrix of dimension 1,000 times 6.

### Details

This package typically start the differential expression analysis with a count table matrix such as `hypoData` where each row indicates the gene (or transcript), each column indicates the sample (or library), and each cell indicates the number of counts to the gene in the sample. The first three columns are produced from biological replicates of, for example, Group 1 and the remaining columns are from Group 2; i.e., G1_rep1, G1_rep2, G1_rep3 vs. G2_rep1, G2_rep2, G2_rep3. This data is generated by the `simulateReadCounts` function with default parameter settings. The first 200 genes are differentially expressed in the two groups. Of these, the first 180 genes are expressed at a higher level in Group 1 (G1) and the remaining 20 genes are expressed at a higher level in G2. Accordingly, the 201-1000th genes are not differentially expressed (non-DEGs). The levels of differential expression (DE) are four-fold in both groups.

### Examples

    # The 'hypoData' is generated by following commands.
    tcc <- simulateReadCounts(Ngene = 1000, PDEG = 0.2,
                              DEG.assign = c(0.9, 0.1),
                              DEG.foldchange = c(4, 4),
                              replicates = c(3, 3))
    hypoData <- tcc$count
