如何使用展开管道（％$％）运算符将R中的两个函数字符串

Question

我想结合这两个功能：

`dataframe %$%
  t.test(vector1, vector2, paired = T)
  cohen.d.(vector1, vector2, paired = T)`

只需要一次只需要data.frame的东西：

{{1}}

Answer 1

只需列出其中的两件事：

attitude %$% list(t.test(rating, complaints), cohen.d(rating, complaints))
[[1]]

        Welch Two Sample t-test

data:  rating and complaints
t = -0.5970993, df = 57.53962, p-value = 0.5527835
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
 -8.560849235  4.627515902
sample estimates:
  mean of x   mean of y 
64.63333333 66.60000000

Cohen's d

d estimate: -0.1541703764 (negligible)
95 percent confidence interval:
          inf           sup 
-0.6717788229  0.3634380702
