datPrep: internal fxn for array data preprocessing

In htc502/ewrefxn: this package collects r fxns useful in my daily coding life

Description

this function is used to extract and prepare the data matrix which will be used to do differential expression calculation. if class1 is set to NULL, the returned value will be used for one class DEG analysis.

Usage

datPrep(dat.mtr, featureName = NULL, sample.label, class1, class2)

Arguments

dat.mtr	an expression data matrix with one column per sample; each gene as a row.
featureName	optional gene name for the expression matrix(vector with length == nrow(dat.mtr)).
sample.label	sample treament(condition) labels for each sample(vector with length == ncol(dat.mtr)).
class1	class1 and class2 are strings indicating which groups are compared.
class2	class1 and class2 are strings indicating which groups are compared.

Value

a list with 3 elements: dat for expression data matrix, cls for the coressponding sample labels, featureName is attached as also.
