Hi everyone,

I am quite new to R.

my command is
t.test(c(1:5,7:11), y=c(1:10),alternative = c("two.sided"), paired = TRUE)

The output is

        Paired t-test

data:  c(1:5, 7:11) and c(1:10)
t = 3, df = 9, p-value = 0.01496
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
 0.1229738 0.8770262
sample estimates:
mean of the differences
According to the reference:

A list with class "htest" containing the following components:
p.value the p-value for the test.

How can I get only the p.value as the output instead of the whole print out?

Thanks a lot!
