如何在RStudio中创建虚拟变量？有数字数据？

Question

JOB 0：失业/非熟练 - 非居民 1：不熟练 - 居民 2：熟练的员工/官员 3：管理/自雇/高素质的员工/官员 历史 0：没有学分 1：该银行的所有信用均已正式偿还 2：现有的学分到目前为止已经还清 3：过去延迟付款 4：关键帐户

Answer 1

首先：RStudio是一个IDE（集成开发环境）。您可能想要使用R（RStudio使用的语言/统计程序，但也可以单独使用）。

您的问题非常明确，但如果（我不确定）您正在寻找使用虚拟变量的方法，例如回归模型，您可以考虑使用因子变量：< / p>

JOB <- factor(sample(1:3, 10, replace = TRUE), 
              levels= 0:3,
              labels = c("unemployed/ unskilled - non-resident",
                         "unskilled - resident",
                         "skilled employee / official",
                         "management/ self-employed/highly qualified employee/ officer"),
              ordered = TRUE
)

将会给你：

 [1] unskilled - resident                                        
 [2] unskilled - resident                                        
 [3] skilled employee / official                                 
 [4] skilled employee / official                                 
 [5] skilled employee / official                                 
 [6] unskilled - resident                                        
 [7] management/ self-employed/highly qualified employee/ officer
 [8] unskilled - resident                                        
 [9] skilled employee / official                                 
[10] management/ self-employed/highly qualified employee/ officer
4 Levels: unemployed/ unskilled - non-resident < unskilled - resident < ... < management/ self-employed/highly qualified employee/ officer

和HISTORY类似。
