One way would be to wrap it in as.vector()

as.vector( t.test(rnorm(5),rnorm(5))$conf.int )
[1] -0.9718231  1.2267976

Or even c():

> c( t.test(rnorm(5),rnorm(5))$conf.int )
[1] -1.055843  1.742806

Dear R People:

When I want to produce a small sample confidence interval using
t.test, I get the following:

t.test(buzz$var1, conf.level=.98)$conf.int
[1] 2.239337 4.260663
attr(,"conf.level")
[1] 0.98

How do I keep the attr statement from printing, please? I'm sure it's
something really simple.

Thanks,
Sincerely,
Erin
