Here is the below data frame. we want to create a data frame like the below. we can create the data frame in a different way, below are the method which you can apply.
# first Method
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)
)
# Second Method
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)
Student <- data.frame(RollNo, Marks, PassOrFail)
> str(Student)
'data.frame': 10 obs. of 3 variables:
$ RollNo : int 1 2 3 4 5 6 7 8 9 10
$ Marks : num 10 20 30 40 50 60 70 80 90 100
$ PassOrFail: logi FALSE FALSE FALSE FALSE FALSE TRUE ...
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
