I have this question I hope you can answer. First, lets see this simple example, using the Student's t-test:

> test<-t.test(miTest.data, mu=0.5, conf.level=0.90 )
> test

         One Sample t-test 

data:  miTest.data 
t = 0.5222, df = 9, p-value = 0.6141 
alternative hypothesis: true mean is not equal to 5 
90 percent confidence interval:
 3.744928 7.255072 
sample estimates:
mean of x 

The question is: what kind of expression should I use to get the confidence interval? That is, what expression should <exp> be, so

> confInterval <- <exp>
> cinfInterval
[1] 3.744928 7.255072

Thanks in advance,
