Hi, I am doing DE miRNA analysis using EdgeR and I need to make a heatmap for the top 50 DE miRNAs, or the most VARIABLE ones.
EdgeR userguide suggests:
logcounts <- cpm(y, log=TRUE)
where y is the DGEList object.
The problem is with labelling, I want the names of miRNAs to show on the heatmap but " y" object takes no names, only counts matrix, and I'm not sure how to annotate it with the miRNA names. Any help?
