Hello Arun,
Thanks so much--while I haven't tried it yet, this seems as though it
will be an excellent way to skip the categories (Actb, etc) that have

This works very well--thanks so much.
By way of extension: how would one extract elements from the result object?
For example:
thing<=apply(Dtb[,3:10], 2, function(x) wilcox.test(x~Dtb$Group))
summary(thing)$p.value
Does not provide a list of p-values as it would in a regression object.

Hi David,
Thank you for the insight: I could have sworn I added a picture of the

I'd suggest that you look into using a time series class to organize your

also make it alot easier to work with your data in specific time-series sort

If I am not wrong the difference is that if you has two levels you get
U-test, and W-test for more than two levels. But the test is almost the

Hi,

But instead of an U-value I get a W-Value.
Is it possible to change this?
