Re: [R] R help for creating expression data of Differentially expressed genes

Hi Arun, I am still facing trouble as I can see the data output is identical for all rows when I am using this merge function. It seems that since in my data2 which I have provided I have not given you the exact genes I have. There are likely to be repeatations of ID in both the files but the pro
