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 read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
