我如何串R中兩個函數與博覽會管道（％$％）運算符

Question

想這兩個功能結合起來：

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

到的東西，需要data.frame只有一次這樣的：

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

Answer 1

只是要與兩件事情的清單中吧：

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

     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
