HKnorm: Normalization to Housekeeping Genes

In AlineTalhouk/nanostringr: Performs Quality Control, Data Normalization, and Batch Effect Correction for 'NanoString nCounter' Data

Normalization to Housekeeping Genes

Description

Normalizes the gene expression of NanoString nCounter data to housekeeping genes. This is done by subtracting the average log housekeeping gene expression from the expression level of every gene in each sample.

Usage

HKnorm(raw, is.logged = FALSE, corr = 1e-04)

Arguments

raw	data frame of raw counts obtained from nCounter (rows represent genes, columns represent samples). The first three columns must be labeled: c("Code.Class", "Name", "Accession") and contain that information.
is.logged	logical; If TRUE, normalization has already been done on log base 2 scale, no need log the data
corr	small correction to avoid error

Value

data frame of log normalized data in the same format but without reference genes
