Error in createMAE function: non-unique values when setting 'row.names' in TCGA LIHC Data

Question

[J. Smith]

Hi friends,

I am working with the createMAE function of ELMER Bioconductor package. While executing the createMAE function using TCGA LIHC DNA Methylation 450K and RNASeq HTSeq - Counts data, I am getting this error:

`Error in.rowNamesDF<-`(x, value = value) :

duplicate 'row.names' are not allowed

In addition: Warning message:

non-unique values when setting 'row.names': 'TCGA-DD-AACA-02A', 'TCGA-DD-AACA-02B'``

Can anyone tell me how to get rid of such error?
