First: RStudio is an IDE (Integrated Development Environment). You probably want to use R (the language/stat program that RStudio uses, but that can also be used independently).

Your question is very unclear but if (which I'm not sure of) you're looking for a way to use dummy variables in for example a regression model, you might instead consider a factor variable:

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
)

Wich will give you:

 [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

and similar for HISTORY.
