runRUV_III_PRPS: Generate RUV-III Data Object

In AbhishekSinha28/tcgaCleaneR: TGCA Data Analysis

Generate RUV-III Data Object

Description

This function is a part of the data analysis functionality of tcgaCleaneR. It captures both the uses PRPS values from library tcgaCleaneR combined with row counts and run SVD algorithm (runSVD()) from BiocSingular on the combined dataset. The function uses RUV-I algorithm from ruv as a pre-processing step to RUV-III.

Usage

runRUV_III_PRPS(
  ruv.data,
  ruv.rep,
  ncg.set,
  k = NULL,
  eta = NULL,
  include.intercept = TRUE,
  average = FALSE,
  fullalpha = NULL,
  return.info = FALSE,
  inputcheck = TRUE
)

Arguments

ruv.data	S4 data object for RUV-III: A S4 data object with combined data including the row count from original filtered data using assay HTseq_counts, prps data for batch and library size. This data needs to be further converted to log scale and transposed.
ruv.rep	S4 data matrix for RUV-III: A S4 data object that has been generated using replicate.matrix functionality from ruv package. This helps ruv to identify replicate samples.
ncg.set	logical object: Set of Negative Controlled genes.
k	Integer scalar specifying the number of unwanted factors to use. Default is NULL. Currently Value 1 represents the library size, 2 represents purity and 3 is time variation.
eta	Gene-wise (as opposed to sample-wise) covariates. A matrix with n columns for ruv::RUV1. Default is NULL.
include.intercept	Add an intercept term to eta if it does not include one already for ruv::RUV1. Default is True.
average	Default is False.
fullalpha	To perform RUV-III calculation. Default is NULL.
return.info	logical: Do you want all the information related to RUV-III object. False gives all information whereas True gives only the
inputcheck	logical: Check the inputs to identify if ruv.data contains missing values or infinite values.

Value

Based on the return.info we get either a S4 list will all information related to RUV-III object or just the RUV-III result.

Examples

## Not run: 
runRUV_III_PRPS(ruv.data = ruv.data, ruv.rep = ruv.rep, ncg.set = ncg.set, k=1, return.info = TRUE)

## End(Not run)
