Good afternoon everybody,
I'm writing a little function to visualise hypothesis testing. Therefore
I need to extract the confidence level of a t-test. Here a little example:
x <- str(t.test(1:10)
gives
List of 9
$ statistic : Named num 5.74
..- attr(*, "names")= chr "t"
$ parameter : Named num 9
..- attr(*, "names")= chr "df"
$ p.value : num 0.000278
$ conf.int : atomic [1:2] 3.33 7.67
..- attr(*, "conf.level")= num 0.95
$ estimate : Named num 5.5
..- attr(*, "names")= chr "mean of x"
$ null.value : Named num 0
..- attr(*, "names")= chr "mean"
$ alternative: chr "two.sided"
$ method : chr "One Sample t-test"
$ data.name : chr "1:10"
- attr(*, "class")= chr "htest"
Now I can use
x$conf.int
what gives
[1] 496.9141 499.6276
attr(,"conf.level")
[1] 0.95
In the example I try to extract the value 0.95 but I have no Idea how. I
hope somebody can help me.
Thanks in advance an greetings from Berlin
Etienne
