Hallo
My output lists more than p-values
> ttt<-t.test(rnorm(10), rnorm(10), paired=T)
> ttt
Paired t-test
data: rnorm(10) and rnorm(10)
t = 1.7508, df = 9, p-value = 0.1139
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
-0.1750263 1.3735176
sample estimates:
mean of the differences
0.5992456
> str(ttt)
List of 9

The output is list and you can call any part of it by its name or by []
braces.
