R help - Oct 2011 - Is it possible to generate an ExpressionSet object that contain duplicate row names?

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
