(e.g. 10 sheets in one excel file) into R and create datasets for all the

Thank you in Advance.
Hello,
One way is to use

Hi Murat,
I am not an expert in either statistics nor R, but I can imagine that

probability, and it may indeed be 0. if you use wilcox.test(x, y,
exact=FALSE) it will give you a normal aproximation, which will most
likely be differen

Thanks for the correction, sorry Murat I was mistaken. Actually your
