ArrayMerge: Merge multiple 'ExpressionSet' objects

In ShixiangWang/iProfile: integrated cancer Profile using multiple datasets

Description

This function is used to merge multiple ExpressionSet objects by Features.

Usage

ArrayMerge(Exprs_list = NULL, Features = NULL, annot = "org.Hs.eg.db")

Arguments

Exprs_list	a list of ExpressionSet objects. They must have same identifier, you can use either gene symbol or gene id. This can be done by ArrayBuildfData.
Features	a character vector at least include all featureNames of Exprs_list. You can get HUGO gene symbol or id from data(hugo).
annot	set a annotation platform or package for merged ExpressionSet object.

Details

The mechanism of biobase package has no function to merge multiple ExpressioSet object. Due to different feature names in different platforms, we use custom Features to construct a uniform feature data.frame.
