Hi, maybe someone can help me with this:
I have a matrix of genes and values: GeneName Value Abc1 10 Abc2 11 Bbc1 -5 Bbc31 2 Ccd 5 Ccd -2 Ccd 7 Dda 5 Dda 10 ..... ..... Zzz3 -1 I would like to create a new matrix where the GeneNames which are duplicated and do not have the absolut maximum value between these duplicated genes, are deleted; i.e. GeneName Value Abc1 10 Abc2 11 Bbc1 -5 Bbc31 2 Ccd 7 Dda 10 ..... ..... Zzz3 -1 Does anyone know if there is a function that works this way in R? How would you do it? Thank you very much in advance!
