Identify likely duplicate samples from genomic or meta-data
Description
The main function is doppelgangR(), which takes as minimal
input a list of ExpressionSet object, and searches all list
pairs for duplicated samples. The search is based on the
genomic data (exprs(eset)), phenotype/clinical data
(pData(eset)), and "smoking guns" - supposedly unique
identifiers found in pData(eset).
