I have RNA-seq expression data of 9 time points. How I can write a function in r to calculate the Euclidean norm of the difference between the gene expression vector at each time point and the previous time point?
One ? at the end of your question is sufficient.
Sorry, what do you mean?
You had multiple ? at the end of your question; it read "previous time point?????". I made the appropriate change and notified you of the change.
