Question

1 : unskilled - resident
2 : skilled employee / official

4: critical account

Answer 1

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.
