scHOT_performPermutationTest

Description

Perform permutation test

Usage

scHOT_performPermutationTest(
  scHOT,
  verbose = FALSE,
  parallel = FALSE,
  BPPARAM = BiocParallel::SerialParam()
)

Arguments

scHOT

A scHOT object

verbose

A logical input indicates whether the intermediate steps will be printed

parallel

A logical input indicates whether run the permutation test using multiple cores in parallel.

BPPARAM

A BiocParallelParam class object from the BiocParallel package is used. Default is SerialParam().

Value

scHOT A scHOT object with results stored in scHOT_output slot
