You may want to search around Biostars and Bioconductor for how to do this and what it means. For a 'philosophical' initial discussion, please read the answers by James and Gordon: Method to get normalized counts in edgeR without cpm.

Lately, as I have been answering many questions on RNA-seq analyses, and in knowing the vagueness of the meaning of the words, I have also somewhat shuddered inside when writing out the words 'normalised count' (or with a 'z', if you're American / Canadian).

Eventually, after searching, you may stumble upon this answer, which should allow you to get what you want: edgeR TMM values.
