In this question we will add a new column to an existing data frame

Here in the existing Data Frame

Student <- data.frame(
RollNo = 1:10,
Marks = c(10, 20, 30, 40, 50, 60, 70, 80, 90, 100), 
PassOrFail = c(F, F, F, F, F, T, T, T, T, T))

In this Data Frame we will add a column StudentName

Program:

> StudentName <- c("Rumman", "Inza", "Jaman", "Azam", "Samser","Kamran","Roman", "Ali", "Ansar", "Sfik")
> Student$StudentName <- StudentName

Output:

> str(Student)
'data.frame':	10 obs. of  4 variables:
 $ RollNo     : int  1 2 3 4 5 6 7 8 9 10
 $ Marks      : num  10 20 30 40 50 60 70 80 90 95
 $ PassOrFail : logi  FALSE FALSE FALSE FALSE FALSE TRUE ...
 $ StudentName: chr  "Rumman" "Inza" "Jaman" "Azam" ...
