Calculating Euclidean distance for a matrix in R

Question

[Za]

Hi,

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?

Za,

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.
