[R] 2 Sample Confidence Interval - Formatting Data?

[Wayne Aldo Gavioli]

Hello all,

I have to run a 2 Sample Confidence Interval on some data; the command for such
intervals is "confint(...)", but in the help documentation it says that you
need a "fitted model object" in order to run this command.  What does that
mean?

The data is very small, it's:

x=c(8,12,10,14,2,0,0)
y=c(-6,0,1,2,-3,-4,2)


and I want to be able to run a Confidence interval for the difference of two
means (x-bar minus y-bar).  Do I have to fit these two pieces of data into some
kind of object?


A little confused,


Wayne
