[FORGED] Re: Issue with t.test

<SNIP>

The only time I have seen t.test give a p-value of 1 is when the
data mean exactly equals the null hypothesis mean and the alternative
is the default of two.sided.

<SNIP>

Doesn't have to be *exact* equality.  Just close!

E.g.:

set.seed(42)
x <- runif(10)
mew <- 0.63626
mew==mean(x) # FALSE
t.test(x,mu=mew)

cheers,
