Hii, I am working on microarray gene expression data analysis. I have agilent one-colour data and I want to filter the genes based on coefficient of variation greater than 0.5 (50%). Do you have any idea how to do that? Please let me know about this.
You use the definition of the CV. The definition is the ratio between the standard deviation to the mean. Hence, you calculate both for each gene (the technical way is dependent on the software you use), and perform the division.
That I already knew but I need to know how we can calculate CV using some R package?
