Dear all,

 

I am facing the problem that comes up when an ExpressionSet object is intended to be created parsing a matrix expression data with duplicate row names:

 

> try(myExpressionSet <- new("ExpressionSet", exprs = myexprsunique, phenoData = myphenoData, annotation = myannotation, check.names=FALSE))

Error in data.frame(numeric(n), row.names = nms) :

  duplicate row.names: blu

 

I was wondering if there exists a way to create this ExpressionSet object although duplicate row names exist in the expression matrix data parsed? Many thanks in advance.

 

Kind regards,

 

Núria
