how to ignore t.test error message

Hello,
I was wondering if there is a way to ignore the error
message you get when some of the data means you
compare are constant in some lines of your data frame.

What does the error message say exactly?
Do you have an example?

Even with the degenerated case
   t.test(c(0, 0), c(0, 0))
I don't get any error message.

I'd like to go ahead with t.test 

See ?try

and get the calculated p-values anyway in such a case.

And what is the p-value in such a case?

I guess I haven't understood the problem correctly, so please be more 
specific!

Uwe Ligges

Thanks
