get_symbol_exprSet: extract the expression matrix from a eSet object

In jmzeng1314/humanid: gene id annotation

Description

not only extract the expression matrix, but change the probeset ID to gene HUGO symbol ,and remove the duplicated genes .

Usage

get_symbol_exprSet(eSet, platformDB = "hgu133plus2.db", filter = TRUE)

Arguments

eSet	A expresstionSet,S4 object in R, which contain: assayData,phenoData,featureData
platformDB	which microarray platform does the eSet use,such as illuminaHumanv4.db, hgu133plus2.db
filter	whether to filter genes show very low expression values, default:TRUE

Value

expression matrix, rowname is the gene HUGO symbol

Examples

#' exprSet <- get_symbol_exprSet(K27M_WT_eSet)
