FEAST_fast {FEAST} | R Documentation

## FEAST main function (fast version)

### Description

FEAST main function (fast version)

### Usage

    FEAST_fast(Y, k = 2, num_pcs = 10, split = FALSE, batch_size = 1000, nProc = 1)

### Arguments

`Y` | A expression matrix. Raw count matrix or normalized matrix.
`k` | The number of input clusters (best guess).
`num_pcs` | The number of top pcs that will be investigated through the consensus clustering.
`split` | boolean. If T, using subsampling to calculate the gene-level significance.
`batch_size` | when split is true, need to claim the batch size for spliting the cells.
`nProc` | number of cores for BiocParallel enviroment.

### Value

the rankings of the gene-significance.

### Examples

    data(Yan)
    k = length(unique(trueclass))
    res = FEAST_fast(Y, k=k)
