Write a R program to add new row(s) to an existing data frame

exam_data = data.frame(
name = c('Anastasia', 'Dima', 'Katherine', 'James', 'Emily', 'Michael', 'Matthew', 'Laura', 'Kevin', 'Jonas'),
score = c(12.5, 9, 16.5, 12, 9, 20, 14.5, 13.5, 8, 19),
attempts = c(1, 3, 2, 3, 2, 3, 1, 1, 2, 1),
qualify = c('yes', 'no', 'yes', 'no', 'no', 'yes', 'yes', 'no', 'no', 'yes')
)
print("Original dataframe:")
print(exam_data)
new_exam_data = data.frame(
name = c('Robert', 'Sophia'),
score = c(10.5, 9),
attempts = c(1, 3),
qualify = c('yes', 'no')
)
exam_data =  rbind(exam_data, new_exam_data)
print("After adding new row(s) to an existing data frame:")
print(exam_data)

Sample Output:

        name score attempts qualify
1  Anastasia  12.5        1     yes
