如何从"htest"提取数据集在r中使用公式时的对象 [英] How to extract the dataset from an "htest" object when using formula in r

问题描述

问题是使用公式时如何从"htest"对象中提取数据集. 例如，

The question is how to extract the dataset from an "htest" object when using formula. For example,

library(gginference)
t_test <- t.test(formula = pulse~ gender,  
             data=questionnaire)
t_test$data.name

返回

[1] "pulse by gender"

是否可以提取数据集(在本例中为问卷")?

Is there a way to extract the dataset (in this case "questionnaire")?

推荐答案

无法从t.test()的输出列表中提取数据. t.test()输出的组件代码是这样的:

There is no way that you could extract the data from the list of the output of t.test(). The code for the components of the output of t.test() is this:

rval <- list(statistic = tstat, parameter = df, p.value = pval,
           conf.int = cint, estimate = estimate, null.value = mu,
           alternative = alternative,
           method = method, data.name = dname)
    class(rval) <- "htest"

您可以看到t.test()的输出列表不包含变量.

You can see that the list of the output of t.test() does not include the variables.
